# CVE-2026-97702: Open edX: Support "manage\_course\_team" REST API omits the \`require\_support\_permission\` gate its sibling support views enforce

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- Known exploited (CISA KEV): no
- Fixed in: release/ulmo.4, release/verawood.1
- Published: 2026-11-04 · Updated: 2026-11-04

CVE-2026-97702 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 5.3 (medium) and affects openedx-platform; fixed in release/ulmo.4 and release/verawood.1.

## Summary

Open edX Platform's support course-team REST API lets any signed-in learner, reached remotely over the network, tell whether an email, username, or user ID belongs to an active account, because the endpoint skips the support-role check its sibling views enforce. A user with an instructor role in a course or organization can also see the target's staff or instructor assignments within that scope.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- openedx openedx-platform: from release/ulmo, fixed in release/ulmo.4; from release/verawood, fixed in release/verawood.1

## Description

Open edX Platform enables the authoring and delivery of online learning at any scale. From the Ulmo release until release/ulmo.4 and release/verawood.1, the GET /api/support/v1/manage_course_team/ endpoint in CourseTeamManageAPIView requires only IsAuthenticated and omits the global support-role authorization check intended for this help-desk surface. Any authenticated learner can supply an email, username, or user_id for an arbitrary target and use the 200 and 404 response discrepancy to distinguish an active account from an absent or inactive account. A caller with a course-level or organization-level instructor role can additionally obtain the target user's staff or instructor assignments within the caller's course or organization scope. Anonymous callers remain blocked, and the separately authorized PUT behavior is outside this vulnerability. This issue is fixed in release/ulmo.4 and release/verawood.1.
