AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Remote HTTP request (AV:N/AC:L) requires an authenticated session (PR:L), no user interaction; impact is unauthorized write to private threads (I:H) with no read/DoS (C:N/A:N).

Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.69.0, authenticated users who are not members of a private space can create content in questions belonging to that space because src/main/java/com/erudika/scoold/controllers/QuestionController.java in QuestionController.reply() and src/main/java/com/erudika/scoold/controllers/CommentController.java in CommentController.createAjax() do not apply the canAccessSpace authorization check used by the question read path. With scoold.is_default_space_public set to false and private spaces in use, a user with a valid session and a known or enumerable question identifier can send requests to POST /question/{id} and POST /comment, causing replies and comments to be stored in a thread the user cannot read. This permits unauthorized modification of private discussions and can trigger notifications that reveal the existence or metadata of private activity. This issue is fixed in version 1.69.0.
AnalysisAI
Missing space-membership authorization checks in Scoold prior to 1.69.0 let any authenticated user write replies and comments into question threads belonging to private spaces they are not members of, resulting in unauthorized modification of private discussions. The flaw only manifests in the non-default configuration where scoold.is_default_space_public is set to false and private spaces are actually in use, and it requires a valid session plus knowledge (or enumeration) of a target question identifier; the attacker gains write access only, not read access, to the affected thread. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a specific non-default deployment: scoold.is_default_space_public must be set to false AND private spaces must be in active use - this is the exact configuration named in the advisory. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate-severity broken-access-control flaw, not a headline emergency, but a genuine correctness/integrity problem for teams relying on Scoold's private spaces. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Scoold 1.69.0 or later, which is the vendor-released patch containing commit 6976afb931d025cf0a35b11d6dff4f699dc87981; the release is published at https://github.com/Erudika/scoold/releases/tag/1.69.0 and the advisory is at https://github.com/Erudika/scoold/security/advisories/GHSA-h2p4-mm8g-whxr (the same commit URL is mirrored in NVD). … Detailed patch versions, workarounds, and compensating controls in full report. |
