EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 2.4%, top 18% 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).

PJSIP is a free and open source multimedia communication library written in C. Versions 2.12 and prior contain a stack buffer overflow vulnerability that affects PJSUA2 users or users that call the API pjmedia_sdp_print(), pjmedia_sdp_media_print(). Applications that do not use PJSUA2 and do not directly call pjmedia_sdp_print() or pjmedia_sdp_media_print() should not be affected. A patch is available on the master branch of the pjsip/pjproject GitHub repository. There are currently no known workarounds.
