| CVE-2026-74765 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 6.5 Medium |
| Net::IDN::Punycode versions before 2.590 for Perl allow an out-of-bounds read via integer overflow of the delta accumulator in encode_punycode. The XS backend keeps the punycode delta, and the digit index derived from it, in a signed int. The accumulation `delta += (m-n) * (h+1)` has no overflow check, so a large enough code point wraps the delta and the digit index leaves the range of the 36-entry digit table. The bound before the final table access tests only for an index above 36, so a negative index passes it, as does 36 itself. Perl strings hold code points beyond the Unicode range, and one such code point overflows the accumulation on its own. Valid input wraps it as well, for example 1927 ASCII letters followed by U+10FFFF. The conversion functions encode a label before they check its length, so a long label reaches the encoder through the documented API. Only the XS backend is affected. Encoding an attacker-supplied string copies a byte from outside the digit table into the encoded result or crashes the process. | ||||
| CVE-2026-74766 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 8.4 High |
| Net::IDN::Punycode versions from 2.301 before 2.590 for Perl allow a heap use-after-free via a decoded code point that reallocates the output buffer in decode_punycode. The XS backend inserts each decoded code point into the string buffer of the scalar it returns. decode_punycode computes the insertion pointer first and only then grows the buffer when the code point does not fit. The growth reallocates the buffer and updates every pointer except the insertion pointer, so the move that follows and the write of the code point go through a freed pointer. The buffer starts at twice the label length, and a code point above U+FFFF takes four bytes in the output, so a label of such code points outgrows it and forces the reallocation. Version 2.301, the fix for CVE-2016-15059, introduced the defect. Only the XS backend is affected. Decoding an attacker-supplied punycode label reads and writes freed heap memory. | ||||
| CVE-2026-87078 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 9.1 Critical |
| Net::IDN::Punycode versions from 2.302 before 2.590 for Perl leak the output buffer on every rejected label in decode_punycode. The XS backend allocates the scalar it returns before it validates the input, sizing the buffer at twice the input length. The scalar is released only on the success path, so each of the three croaks that reject a label leaves the scalar and its buffer allocated. Nothing bounds the label length in the to-Unicode direction, since the 63-byte DNS limit is checked only when converting to ASCII. Only the XS backend is affected. A sender who supplies invalid labels grows the process by twice the label length per rejected call, with no successful call needed. | ||||
| CVE-2026-87079 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 7.5 High |
| Net::IDN::Punycode versions before 2.590 for Perl allow CPU exhaustion via quadratic insertion cost when decoding a long label in decode_punycode. The XS backend inserts each decoded code point into a UTF-8 buffer and finds the insertion point by scanning that buffer from the start, one character at a time. The scan runs once per code point over the output built so far, so the cost is quadratic in the label length. The pure-Perl backend downgrades its input to bytes so that substr can index it directly, but takes its working copy before the downgrade, so when the input carries the UTF-8 flag every substr on the copy scans from the start, with the same quadratic cost. Nothing bounds the label length in the to-Unicode direction. The 63-byte DNS limit is checked only when converting to ASCII, so domain_to_unicode and uts46_to_unicode pass an attacker-supplied label of any length to the decoder. | ||||
| CVE-2026-87080 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 9.1 Critical |
| Net::IDN::Punycode::PP versions before 2.590 for Perl decode a truncated label to a name containing a character it never encoded in decode_punycode. The pure-Perl decoder reads one digit at a time with four-argument substr and tests the result with defined to detect the end of the input. substr on an exhausted string returns the empty string rather than undef, so decoding continues past the end. The empty string converts to a digit value below the range, reducing the accumulator, and the decoder derives one extra code point and its position from it. The result is deterministic. The XS backend rejects the same label. Net::IDN::Punycode uses this backend wherever the XS does not build. The two backends disagree about what such a label means, so a sender can pick a label that one installation resolves to a name and another rejects. | ||||
| CVE-2026-87081 | 1 Perl | 1 Net::idn::uts46 | 2026-09-29 | 7.5 High |
| Net::IDN::UTS46 versions before 2.590 for Perl allow CPU exhaustion via quadratic punycode encoding of an overlong label before the length check in to_ascii. to_ascii punycode encodes each label and only then applies the 63-byte DNS limit. encode_punycode in both backends follows the sample implementation in RFC 3492, whose outer loop runs once per distinct non-ASCII code point and scans the whole input each round, so a label of distinct non-ASCII characters costs the square of its length before the limit rejects it. Every ASCII conversion in the distribution, including domain_to_ascii and email_to_ascii, goes through to_ascii. | ||||
| CVE-2026-87082 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 7.5 High |
| Net::IDN::Punycode versions before 2.590 for Perl hang, crash or return a wrong label via unvalidated malformed UTF-8 in encode_punycode. Neither backend checks that its input is well-formed UTF-8, so a string with the UTF-8 flag set over malformed bytes, as the :utf8 PerlIO layer produces from any malformed input, reaches the encoder unchecked. On perl 5.32 and later the XS backend reports a malformed sequence with a length of `(STRLEN)-1`, so the scan steps back one byte instead of forward and never ends. On earlier perls the XS returns a valid label for a different name. The pure-Perl backend runs a regex over the flagged string. Depending on the bytes, it aborts with SIGBUS on perl 5.28 and later, dies with a panic, or returns a wrong label. The documented conversion functions match the label against Unicode properties first and that match dies on such a string, so only a direct call to encode_punycode reaches the defect. The decoder is not affected. A direct caller encoding attacker-supplied bytes hangs, crashes or gets a label for a name the input never held. | ||||

| CVE-2026-97227 | 1 Wordpress-extensions | 1 Nextscripts Social Networks Auto-poster | 2026-09-29 | 5.9 Medium |
| The NextScripts: Social Networks Auto-Poster WordPress plugin before 4.4.8 does not perform capability or ownership checks on several of its AJAX actions, relying on a nonce alone, allowing users an administrator has granted access to its posting features to export the site's configured social account credentials, delete arbitrary posts and reset the NextScripts: Social Networks Auto-Poster WordPress plugin before 4.4.8's configuration. | ||||
| CVE-2026-85644 | 1 Perl | 1 Xs::parse::infix | 2026-09-29 | 7.5 High |
| XS::Parse::Infix versions from 0.40 through 0.49 for Perl treat a number as an array reference. The wrapper function XS::Parse::Infix generates for a list-associative infix operator checks whether arguments are array references, but it tests using SvRV() rather than SvROK(). SvRV() reads a union slot that only holds a referent once SvROK(sv) is true, so the guard never validates that it is a reference. For an IV or NV that slot holds the number itself, SvRV() returns the caller's value and SvTYPE() dereferences it at offset 12. This will generally result in a segmentation fault. An application that hands the wrapper a list built from decoded input (for example, from JSON) lets whoever supplies a number in that list choose the address that the interpreter dereferences. An ordinary string's byte 12 is rarely SVt_PVAV so the guard croaks by luck, but an attacker-crafted string carrying 0x0b there passes, and the buffer is then used as an AV head, with AvARRAY taken from bytes 16-23 and its entries pushed onto the Perl stack as live SVs. A simple proof-of-concept uses the zip operator: use Syntax::Operator::Zip 'zip'; my @args = ([1], 2); zip(@args); | ||||

| Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Vehicle Manager (Free) < 6.5.8 - site/vehiclemanager.php reads the order_field and order_direction sort parameters at three separate anonymous-reachable frontend entry points (category listing, search, and the all-vehicles listing) through a sanitizing function that applies real escaping, but the value is then placed into an unquoted ORDER BY clause, where escaping has no protective effect. | ||||
| CVE-2026-84894 | 1 Meta Platforms Inc | 1 Moxygen | 2026-09-29 | N/A |
| In moxygen before commit 004123dd24c3, MoQSession::dataStreamReadLoop keeps using a stream read handle after reading a FIN, which invalidates the handle under proxygen's WebTransport API. A remote peer can trigger the stale use by opening a data stream that names an unknown track alias and carries the FIN in the same write. | ||||
| CVE-2026-100752 | 1 Ordasoft.com | 1 Real Estate Manager (free) Extension For Joomla | 2026-09-29 | N/A |
| Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Real Estate Manager (Free) < 6.7.9 - site/realestatemanager.php builds the ORDER BY clause of three separate frontend property-listing queries (category browsing, search results, and the full property listing) from a request-controlled order_field parameter, concatenated directly into an unquoted SQL clause with no allow-list of real column names and no cast. | ||||
| CVE-2026-100753 | 1 Ordasoft.com | 1 Real Estate Manager (free) Extension For Joomla | 2026-09-29 | N/A |
| Joomla Extension - ordasoft.com - Reflected Cross-Site Scripting in Real Estate Manager (Free) < 6.7.9 - The public property-detail page’s “leave a review” form repopulates its title field directly from the request with no escaping and no filtering function of any kind, unlike the adjacent comment field on the same form, which at least receives partial tag-stripping. A " character in the title query parameter breaks out of the HTML attribute the value is placed in, allowing a following <script> element to execute in the browser of anyone who loads the crafted link. | ||||
| CVE-2026-101110 | 1 Ordasoft.com | 1 Book Library (free) Extension For Joomla | 2026-09-29 | N/A |
| Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6 - site/booklibrary.php’s books() function reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect. | ||||
