02 Description
MISP: Forced TOTP Enrolment Bypassed via Non-Browser Request Types on otp_required Instances
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 0.31% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 24.1% of scored records. A rank, not a probability.
- NVD base score
- 7.1 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation
The TOTP enrolment enforcement in the user verification path was extended from covering only standard browser requests to covering all non-browser request types (AJAX, REST, .json, automation). Any request that cannot follow the browser redirect to the TOTP setup page is now refused with a 403 Forbidden response if the user has not enrolled in TOTP and the instance requires it. Identities authenticated via API key remain exempt, as they are not browser sessions subject to the redirect-based enrolment flow.
