CVE-2026-25699: Apache Answer: Authorization Bypass in Timeline API

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.40% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache Answer 2.0.1.

Low priority for now. Upgrade to Apache Software Foundation Apache Answer 2.0.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Exposure of Private Personal Information to an Unauthorized Actor vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. Timeline-related APIs lacked proper authorization checks, allowing regular authenticated users to access deleted, private, or unapproved content and its revision history. Users are recommended to upgrade to version 2.0.1, which fixes the issue.
