Status: DeferredMedium (6.9)—

Severity6.9Medium · CVSS 4.0

Exploitation probability0.31 %higher than 22% of CVEs

Active exploitationNonot in the CISA catalog

Public exploitNot knownno public code found

A vulnerability was determined in OpenSIPS up to 3.6.8/4.0.1. The impacted element is the function rtpproxy_offer/rtpproxy_answer of the component rtpproxy. This manipulation causes out-of-bounds read. The attack may be initiated remotely. Upgrading to version 3.6.9 and 4.0.2 is sufficient to resolve this issue. It is advisable to upgrade the affected component.

CVSS

Base score: 6.9
Version: 4.0
Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.31 %
Percentile among all scored CVEs: 22
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
