CVE-2026-94114: Apache Commons BCEL: Class repositories cache class files under their self-declared names, enabling cache poisoning

HighCVSS 8.2 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache Commons BCEL 14890bf2b9014df25f9b4de86f29b5e917e5656b, 6.13.0.
  • Severity is disputed: the assigning authority (CNA) scores it 5.9, NVD 8.2.

Low priority for now. Upgrade to Apache Software Foundation Apache Commons BCEL 14890bf2b9014df25f9b4de86f29b5e917e5656b, 6.13.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Symbolic name not mapping to correct class. 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 BCEL: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue.
