Last modified

CVE-2026-10629 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. SIP signaling stack in Verizon IMS (unspecified version) implements SIP signaling without IPsec integrity protection (missing Security-Client/Security-Server headers and ESP traffic), which allows an on-path attacker to compromise confidentiality, integrity, and authenticity of VoLTE signaling via passive monitoring and active manipulation of unsecured SIP messages over the radio and core network.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
