CVE-2026-33710

CWE-330Published: April 10, 2026· Updated: Apr 16, 2026

7.5

CVSS v3.1

Official Description

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, REST API keys are generated using md5(time() + (user_id * 5) - rand(10000, 10000)). The rand(10000, 10000) call always returns exactly 10000 (min == max), making the formula effectively md5(timestamp + user_id*5 - 10000). An attacker who knows a username and approximate key creation time can brute-force the API key. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.

Technical Analysis

CVE-2026-33710 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 7.5.

A proof-of-concept (PoC) exploit exists for CVE-2026-33710. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
