FKIE_CVE-2026-57074

Vulnerability from fkie_nvd - Published: 2026-07-16 17:16 - Updated: 2026-07-16 20:16
Severity
Summary
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.
