CVE-2026-103109: CWE-787 Out-of-bounds Write in Pexip Infinity
Pexip Infinity versions before 38.2, as well as versions 39.0, 39.1, and 40.0, contain a vulnerability due to improper input validation in the media implementation. This flaw allows a remote attacker to send a crafted media stream that can cause memory corruption or trigger a controlled software abort, resulting in denial of service. The vulnerability is identified as CWE-787 (Out-of-bounds Write) and has a CVSS 3.1 score of 7.7, indicating high severity.
AI Analysis
Technical Summary
CVE-2026-103109 is an out-of-bounds write vulnerability in Pexip Infinity's media processing component. Improper input validation allows a remote attacker to craft media streams that can corrupt memory or cause the software to abort during processing. This can lead to denial of service and potentially more severe impacts due to memory corruption. The affected versions include all releases prior to 38.2, and specifically versions 39.0, 39.1, and 40.0.
Potential Impact
Successful exploitation can cause denial of service by triggering a controlled software abort. Additionally, memory corruption may be achieved, which could lead to further compromise of the affected system. The vulnerability is remotely exploitable without authentication but requires high attack complexity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Users should monitor Pexip's official channels for updates and apply patches once available. Until then, consider restricting exposure of the media processing interfaces to untrusted networks to reduce risk.
