Summary
Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-94114: Symbolic name not mapping to correct object vulnerability in Apache Commons. BCEL caches attacker-controlled classes under their self-declared names without validating the requested name, allowing subsequent lookups and name-keyed verification results to refer to a different class. This issue affects Apache Commons: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue. CVE-2026-105111: Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Apache Commons BCEL. This only happens when you're using Class2HTML to generate webpages for possibly-attacker-controlled class files, where Class2HTML emitters write attacker class-file strings into HTML unescaped (stored XSS in reports). This issue affects Apache Commons BCEL: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue.
