MediumCVSS 6.9 · v4.0—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 0.56% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: Openpanel-dev openpanel 3.0.0.

Low priority for now. Upgrade to Openpanel-dev openpanel 3.0.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

OpenPanel before 3.0.0 contains a missing authentication vulnerability that allows unauthenticated attackers to access the Bull Board dashboard served on the worker HTTP port. Attackers can query /api/queues and call mutating Bull Board APIs to add, retry, or clean jobs and read queue data, metrics, and datastore health.
