AI Analysis
Technical Summary
CVE-2026-92399 describes a heap-based buffer overflow in the rmt_client_handle_ws_frame function of the src/utils/rmt_ws.c file in GPAC 26.07.0's WebSocket Handler component. The vulnerability arises from improper handling of the payload_size argument, allowing remote attackers to cause a buffer overflow. Public exploit code is available. The issue is resolved by upgrading to version abi-16.26, which includes the patch identified by commit 37bccbb30cf53a0e1a084cea9a1ce422b3ddfe12.
Potential Impact
Successful exploitation can lead to a heap-based buffer overflow, potentially allowing an attacker to execute arbitrary code or cause a denial of service remotely. The CVSS 3.1 score is 7.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade the affected GPAC component to version abi-16.26 or later, which contains the official patch (commit 37bccbb30cf53a0e1a084cea9a1ce422b3ddfe12) that mitigates this vulnerability. No other mitigation steps are indicated by the vendor advisory.
