CVE-2026-57074: CWE-125 Out-of-bounds Read in CODECHILD XML::Bare
XML::Bare versions through 0.53 for Perl have an unbounded character lookahead. The parserc_parse function attempts to check for multicharacter strings such as "<![CDATA" or element terminators such as ">" without checking that the offsets are within the buffer. Truncated strings such as "<a/" can trigger an out-of-bounds read.
AI Analysis
Technical Summary
The vulnerability in XML::Bare (<=0.53) arises from the parserc_parse function performing character lookahead to identify sequences such as "<![CDATA" or element terminators like ">" without confirming that the offsets accessed are within the input buffer. This lack of boundary checking can cause an out-of-bounds read (CWE-125) when processing truncated XML strings, potentially leading to memory access violations.
Potential Impact
An out-of-bounds read can lead to application crashes or undefined behavior when parsing malformed or truncated XML input. No known exploits are reported in the wild. The vulnerability may affect the stability and reliability of applications using the affected XML::Bare versions.
Mitigation Recommendations
No official patch or remediation is currently available. Users should monitor the vendor or CPAN security advisories for updates. Until a fix is released, avoid processing untrusted or malformed XML inputs with affected versions of XML::Bare.
