Questions about CVE-2026-120199
What does this mean?
An authenticated user can read other users' assignment grades, submitted assignment work, and instructor feedback through the Assignment Submissions API. The API does not properly check authorization, so the data of other users is exposed.Source: github.com
Am I affected, and how do I check?
LearnHouse versions before 1.1.1 are listed as affected. The exposure requires the attacker to be a co-enrolled user of the same course, since any reader of a course is granted course read access, including published or public courses and UserGroup members. To check a installation's version, look at the LearnHouse release in use and compare it with 1.1.1.Source: github.com
What should I do about it?
Upgrade LearnHouse to version 1.1.1 or later, which is the listed fixed version. No fix is listed in the checked facts beyond that version.Source: github.com
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
