Cap-go prior to 12.128.2 contains an account takeover vulnerability in its email change mechanism that allows an attacker with temporary authenticated session access to change the registered email address without re-authentication such as password or MFA verification. Attackers can redirect verification to an attacker-controlled email address and subsequently perform a password reset to permanently take over the victim's account.
CVE-2026-53981
This high-severity CVE scores 7.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
