CVE-2026-34824: CWE-125: Out-of-bounds Read in mesop-dev mesop
Mesop versions 1. 2. 3 up to but not including 1. 2. 5 contain a vulnerability in the WebSocket implementation where an unauthenticated attacker can cause uncontrolled resource consumption by sending rapid WebSocket messages. This triggers the server to spawn excessive OS threads, leading to thread exhaustion and out-of-memory errors, resulting in a denial of service. The issue is fixed in version 1. 2. 5.
AI Analysis
Technical Summary
The Mesop Python-based UI framework versions from 1.2.3 to before 1.2.5 have an uncontrolled resource consumption vulnerability in their WebSocket implementation. An unauthenticated attacker can send a rapid succession of WebSocket messages, causing the server to spawn an unbounded number of operating system threads. This leads to thread exhaustion and out-of-memory conditions, causing a complete denial of service for applications built on the framework. The vulnerability is tracked as CWE-125 (Out-of-bounds Read) and has a CVSS 3.1 score of 7.5 (high severity). The issue has been patched in version 1.2.5.
Potential Impact
Successful exploitation results in denial of service due to thread exhaustion and out-of-memory errors on the server hosting applications built with the affected Mesop versions. There is no impact on confidentiality or integrity, only availability is affected. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade Mesop to version 1.2.5 or later, where this vulnerability has been patched. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor's versioning information.
