Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was found in karakeep-app karakeep up to 0.32.0. The affected element is the function authorize of the file apps/web/server/auth.ts of the component Login Endpoint. The manipulation results in improper restriction of excessive authentication attempts. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is described as difficult. The exploit has been made public and could be used. Upgrading to version 0.33.0 is sufficient to fix this issue. The patch is identified as f7d042971d0d2bcc7119654830cf1eb93eabbf24. It is advisable to upgrade the affected component.
AnalysisAI
Unlimited authentication attempts against the karakeep login endpoint (apps/web/server/auth.ts) in versions up to 0.32.0 enable remote credential brute-forcing due to a missing rate-limiting guard on the NextAuth authorize function (CWE-307). The CVSS 4.0 score of 2.9 with AC:H reflects that successful exploitation depends on the target account holding a guessable password - a condition outside the attacker's direct control. …

Vulnerability AssessmentAI
| Exploitation | The login endpoint is network-reachable and requires no prior authentication or session state, making the attack surface accessible to any remote actor (PR:N in both CVSS assessments). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base vector AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N yields a score of 2.9, placing this at the low end of severity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker enumerates a publicly exposed karakeep instance and identifies a registered user's email address from a prior data breach or public profile. Using an automated credential-stuffing tool seeded with commonly leaked passwords, the attacker submits thousands of unauthenticated POST requests to the login endpoint with no server-side throttle to interrupt them. … |
| Remediation | Upgrade to karakeep version 0.33.0, available at https://github.com/karakeep-app/karakeep/releases/tag/mcp/v0.33.0 (patch commit f7d042971d0d2bcc7119654830cf1eb93eabbf24). … Detailed patch versions, workarounds, and compensating controls in full report. |
