CVE-2026-10860: MISP CRUDComponent delete validation bypass via operator precedence error
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- No fixed version is recorded, but the references include a patch (commit or PR) link.
Low priority for now. See the fix and affected versions sections below.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.
