CVE-2026-114619
Authlib: OpenID implicit grant checks raw scope instead of allowed scope before issuing ID tokens
02 Description
Authlib: OpenID implicit grant checks raw scope instead of allowed scope before issuing ID tokens
03 Exploitation and scoring
- Exploitation
- Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.
- SSVC decision
- ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.15% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 4.4% of scored records. A rank, not a probability.
- NVD base score
- 4.6 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N
- NVD analysis status
- Undergoing Analysis. NVD last modified this record on 2026-10-29.
- Red Hat severity
- Moderate. Red Hat's rating for its own products, not a CVSS rating.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
