MISP Privilege Escalation: Read-Only API Key User Can Regain Full Role via updateLoginTime
CVSS 4.0 8.7 HIGHCheck source for fixed versionsKEV status unknown
cve-program · CVE-2026-94381
PublishedMISP has a security issue that can let a user gain more access than their API key is supposed to allow. A read-only API key should only let someone view information. However, after logging in with such a key, a specific MISP function could accidentally restore the user’s normal account permissions. This means someone with a read-only API key could potentially gain write, delete, or even administrator access if their underlying account has those permissions. Exploiting the issue requires a valid read-only API key and a single request to the affected function. The main impact is that MISP’s API key restrictions can be bypassed, allowing actions that the API key was specifically meant to prevent. Version affected: <2.5.47

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
