7.6 HIGH

PR:L because a low-privileged authenticated user self-escalating is the essence of CWE-269 (not PR:H); escalation primarily grants integrity control (I:H) over roles/data with some confidentiality/availability effect.

DescriptionCVE.org

A vulnerability was determined in aiyiyi121 SxDevOps 1.0/1.1. This affects the function update of the file backend/rbac/serializers.py of the component UserSerializer. Executing a manipulation can lead to improper privilege management. The attack can be executed remotely. This patch is called 2b4bf8585c3e731e7a8af30801ea46680bc783f9. It is best practice to apply a patch to resolve this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

AnalysisAI

Improper privilege management in SxDevOps 1.0/1.1 allows an authenticated user to escalate their own privileges by manipulating the update path of the UserSerializer in backend/rbac/serializers.py, reachable remotely over the network against the RBAC user-update API. The vulnerability is rated medium (CVSS 4.0 base 5.1, AV:N/AC:L/PR:H/UI:N/VC:N/VI:L/VA:L), with the main impact being integrity of role/permission data; a public exploit has not been identified at time of analysis and there is no CISA KEV listing. …

Vulnerability AssessmentAI

Exploitation Requires a valid authenticated account on the SxDevOps application and network reachability to the RBAC user-update API endpoint (UserSerializer.update in backend/rbac/serializers.py). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Vendor (VulDB) rates this CVSS 4.0 5.1 with vector AV:N/AC:L/PR:H/UI:N/VC:N/VI:L/VA:L - medium severity, low integrity/availability impact only. … 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 Apply the upstream fix in commit 2b4bf8585c3e731e7a8af30801ea46680bc783f9 (https://github.com/aiyiyi121/sxdevops/commit/2b4bf8585c3e731e7a8af30801ea46680bc783f9), which closes the UserSerializer privilege-management gap; the vendor states a fixed version was released, though a specifically tagged patched release version is not independently confirmed from the available data, so verify against the repository before assuming an upgrade tag exists. … Detailed patch versions, workarounds, and compensating controls in full report.
