Network API reachable at low complexity but needs a valid personal token (PR:L); leak of private discussions is confidentiality-only, so I:N/A:N, matching the vendor 6.5.

DescriptionCVE.org

Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.69.0, users with personal API tokens can retrieve replies from questions in private spaces they cannot access because src/main/java/com/erudika/scoold/api/ApiController.java in ApiController.getPostReplies() does not apply canAccessSpace before returning data from GET /api/posts/{id}/answers. The issue is reachable when scoold.api_user_access_enabled and scoold.api_enabled are true and a token holder knows or enumerates a private question identifier. Under those conditions, the question endpoint can deny access while the answers endpoint returns the private reply bodies, exposing confidential team or project discussions. This issue is fixed in version 1.69.0.

AnalysisAI

Scoold deployments prior to 1.69.0 expose replies to questions in private spaces through the answers API: a holder of a valid personal API token can call GET /api/posts/{id}/answers and receive the reply bodies of a private-space question whose own endpoint correctly denies access. The flaw affects instances configured with both scoold.api_enabled and scoold.api_user_access_enabled set to true, and exploitation additionally requires the attacker to know or enumerate the target question's identifier, so it is a confidentiality-only (C:H, no I/A) disclosure of existing private discussion content rated 6.5. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the Scoold instance has both scoold.api_user_access_enabled and scoold.api_enabled set to true (the user-facing API mode), and the attacker must hold a valid personal API token and know or enumerate the identifier of a specific private-space question. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but moderate-severity confidentiality issue, not an over-scored one. … 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 Scoold to 1.69.0, the version in which the missing canAccessSpace() check is added to the replies endpoint and to adjacent comment and reply handlers; the vendor-released patch is the definitive fix and the remediation target for all pre-1.69.0 deployments (release: https://github.com/Erudika/scoold/releases/tag/1.69.0, advisory: https://github.com/Erudika/scoold/security/advisories/GHSA-2cff-ppf7-pc42). … Detailed patch versions, workarounds, and compensating controls in full report.
