EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of lunary-ai/lunary you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
In lunary-ai/lunary version 1.2.4, a vulnerability exists in the password recovery mechanism where the reset password token is not invalidated after use. This allows an attacker who compromises the recovery token to repeatedly change the password of a victim's account. The issue lies in the backend's handling of the reset password process, where the token, once used, is not discarded or invalidated, enabling its reuse. This vulnerability could lead to unauthorized account access if an attacker obtains the recovery token.

The underlying weakness: Weak Password Recovery Mechanism for Forgotten Password
The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
How developers prevent this class of flaw
- Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
- Do not use standard weak security questions and use several security questions.
- Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
