High CVSS 8.1
CVE-2026-59713
Leantime contains an OIDC login CSRF vulnerability in the verifyState() method that unconditionally returns true without validating state parameters. Attackers can craft malicious callback URLs with attacker-controlled authorization codes to perform session fixation, logging victims in as the attacker.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can read sensitive data and modify or destroy data.
- Weakness
- A request forged from another site executes using the victim’s session (CSRF).
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
