Prior to commit 3a5ac85, a security vulnerability has been identified in the Open edX LMS platform&#39;s LTI (Learning Tools Interoperability) Provider implementation. The validate_timestamp_and_nonce function in lms/djangoapps/lti_provider/signature_validator.py does not validate OAuth nonces or timestamps, allowing an attacker who captures a valid LTI launch request to replay it an unlimited number of times without detection. This issue has been patched via commit 3a5ac85.</p> <p>Open edX Platform enables the authoring and delivery of online learning at any scale.
