CVE-2026-45100

OpenSIPS is a Session Initiation Protocol SIP server implementation. Versions 3.4.0-beta through 3.6.5 and 4.0.0-beta contain a buffer overflow in the s.b64encode string transformation. The size check for s.b64encode only verifies that the input fits within the 64 KB transformation buffer, but...

CVE-2026-45100

OpenSIPS contains a buffer overflow in the s.b64encode transformation affecting versions 3.4.0-beta through 3.6.5 and 4.0.0-beta. The 64 KB transformation buffer is overflowed because base64 encoding expands input by ~33%, so inputs around 49,153–65,535 bytes can overflow and overwrite adjacent m...
