CVE-2026-54676 — Scoold: GET /api/posts/{id}/answers leaks private-space replies when personal API tokens are enabled
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.4% (30-day exploitation probability)+5
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Erudika Scoold).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N (score shown at the top: security-advisories@github.com) Weakness MITRE
Weakness class according to MITRE’s CWE catalog.
Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Audit administrative actions and access to resources outside each user’s normal pattern.

What should defenders know first?
CVE-2026-54676 is "Scoold: GET /api/posts/{id}/answers leaks private-space replies when personal API tokens are enabled", rated Medium. It affects Scoold (Erudika); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.5 describes technical severity. EPSS 0.40% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
