Network-reachable deletion endpoint with no auth check gives PR:N and AC:L, but CSRF/session abuse needs a victim's action so UI:R; impact is account destruction, hence I:H and A:H with C:N.

Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains an authentication bypass vulnerability in the account deletion endpoint that allows deletion without password re-authentication or secondary verification. Attackers can delete user accounts via session hijacking, CSRF attacks, or parameter tampering, resulting in unauthorized account deletion, data loss, and denial-of-service.
AnalysisAI
Account takeover-style destruction in Capgo before 12.128.2 lets remote attackers delete arbitrary user accounts because the deletion endpoint enforces no password re-authentication or secondary verification (CWE-306, Missing Authentication for a Critical Function). Reported by VulnCheck, the flaw is exploitable through CSRF, session hijacking, or parameter tampering, causing irreversible account removal, data loss, and denial-of-service. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerable target is Capgo's account-deletion endpoint, which performs the delete without password re-authentication, a secondary verification step, or a CSRF anti-forgery token. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H) scores 7.0 (High): network-reachable, low complexity, no privileges, but requiring victim interaction, with high integrity and availability impact and no confidentiality loss - consistent with a CSRF/session-abuse destructive action rather than data theft. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page containing a hidden auto-submitting form (or image/fetch request) targeting Capgo's account-deletion endpoint and lures an authenticated Capgo user to visit it; because no CSRF token or password confirmation is required, the victim's browser silently submits the deletion using their live session. Alternatively the attacker tampers with an account/user identifier parameter or replays a hijacked session to delete accounts directly. … |
| Remediation | Upgrade to Capgo 12.128.2 or later, which is the first fixed release per the GitHub Security Advisory GHSA-cjvr-jxp5-4p9x (https://github.com/Cap-go/capgo/security/advisories/GHSA-cjvr-jxp5-4p9x); this is the primary and authoritative fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Inventory all Capgo instances and confirm version numbers below 12.128.2; establish incident response team to monitor for unusual account deletion patterns. …
