Description

YesWiki before 4.6.7 contains an authorization bypass vulnerability in the comments API editComment route that allows authenticated low-privilege users to overwrite arbitrary pages or comments by supplying their own page as the pagetag field. Attackers can send a POST request to the api/comments endpoint targeting a victim tag, bypassing per-page write ACLs to replace content and reparent existing pages or comments.

Detection & mitigation playbook

Vulnerability

  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Remediation status

    No fixed release is recorded for CVE-2026-104444 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
