lunary-ai/lunary: Improper Resolution of Path Equivalence
CVE-2024-8765 is a high-severity improper resolution of path equivalence vulnerability in lunary-ai/lunary from Lunary-ai, with a CVSS 3.0 base score of 7.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.4.23 as the first without the flaw, so updating lunary-ai/lunary to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.84% chance of exploitation within 30 days, higher than 59% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update lunary-ai/lunary to 1.4.23 or a later version.
- Update Lunary to 1.4.23 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
In lunary-ai/lunary, the privilege check mechanism is flawed in version git afc5df4. The system incorrectly identifies certain endpoints as public if the path contains '/auth/' anywhere within it. This allows unauthenticated attackers to access sensitive endpoints by including '/auth/' in the path. As a result, attackers can obtain and modify sensitive data and utilize other organizations' resources without proper authentication.

The underlying weakness: Improper Resolution of Path Equivalence
The product is vulnerable to file system contents disclosure through path equivalence. Path equivalence involves the use of special characters in file and directory names. The associated manipulations are intended to generate multiple names for the same object.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
