Description

A vulnerability was detected in Mayan EDMS up to 4.10.1. The affected element is an unknown function of the file /authentication/. The manipulation results in cross site scripting. The attack may be performed from remote. The exploit is now public and may be used. Upgrading to version 4.10.2 is sufficient to fix this issue. You should upgrade the affected component. The vendor confirms that this is "[f]ixed in version 4.10.2". Furthermore, that "[b]ackports for older versions in process and will be out as soon as their respective CI pipelines complete."

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every mayan-edms mayan edms deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Fix

    Apply the mayan-edms mayan edms security patch or hotfix for CVE-2025-14691 on the affected version, following the vendor advisory for your exact build.

  3. Workarounds

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2025-14691 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2025-14691. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
