CVE-2022-26499 describes a Critical Server-Side Request Forgery (SSRF) vulnerability in Asterisk versions through 19.x, including Debian and Digium distributions. This flaw allows an attacker to send arbitrary requests to internal interfaces, such as localhost, by manipulating the Identity header during STIR/SHAKEN usage. With a CVSS score of 9.1, this vulnerability poses a significant risk due to its network-based attack vector, low complexity, and potential for high impact on confidentiality and integrity. While no public exploit code or active exploitation has been observed, and community discussion is minimal, organizations using affected Asterisk versions should prioritize patching to versions 16.25.2, 18.11.2, or 19.3.2.
