DescriptionCVE.org

streama contains an insecure direct object reference vulnerability in ViewingStatusController that allows authenticated users to read and delete other users' viewing status records. Attackers can enumerate all users' watch progress, delete arbitrary viewing history, and manipulate other users' Continue Watching dashboards by supplying arbitrary primary keys without ownership verification.

AnalysisAI

Insecure direct object reference in streama's ViewingStatusController exposes all authenticated users' viewing history to lateral enumeration, deletion, and manipulation by any peer authenticated user. The list endpoint previously returned all users' ViewingStatus records without filtering, and read, update, and delete operations accepted arbitrary primary keys without ownership verification, enabling cross-user data access. …

Corrupt or erase targeted users' watch progress and Continue Watching dashboards

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated user account on the target streama instance (confirmed by PR:L in the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N) scores 5.3 and accurately reflects a medium-severity issue requiring authentication (PR:L) with limited confidentiality and integrity impact on the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated streama user issues a GET request to the ViewingStatusController list endpoint and receives all other users' viewing records in the response, since the unpatched endpoint performs no user filtering. The attacker then iterates through the returned record IDs, issuing DELETE requests to wipe targeted users' watch progress, or crafting UPDATE requests to corrupt their 'Continue Watching' dashboards. …
Remediation Apply upstream fix commit `1fa79534ee09e25f2473cc4787b106996008a442` from the streama GitHub repository (https://github.com/streamaserver/streama/commit/1fa79534ee09e25f2473cc4787b106996008a442). … Detailed patch versions, workarounds, and compensating controls in full report.
