Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-8p2f-fx4q-75cx plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
In Unopim, it is possible to create roles and choose the privileges. However, users without the “Delete” privilege for Products cannot delete a single product via the standard endpoint (expected behavior), but can still delete products via the mass-delete endpoint, even when the request contains only one product ID.
Severity: High CVSS Score 8.1 (CVSS 3.1 Vector: AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H) Category: Broken Access Control / Missing Authorization (OWASP A01:2021) Impact: Unauthorized product deletion -> data loss, possible business disruption
Affected Behavior
Single delete (enforced):
DELETE /admin/catalog/products/{id} returns 401 with "This action is unauthorized" for users lacking the Delete privilege.
Mass delete (not enforced):
POST /admin/catalog/products/mass-delete allows deletion without the Delete privilege. This occurs for both multiple IDs and a single ID submitted to the bulk endpoint.
PoC
A video was captured in Burp Suite for a proof of concept. The cookies were used directly from Burp Suite and rendered the My Account page to prove what cookies belong to what users. The video PoC is listed in references.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for unopim/unopim, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update unopim/unopim to 0.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8p2f-fx4q-75cx is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-8p2f-fx4q-75cx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-8p2f-fx4q-75cx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-8p2f-fx4q-75cx in your dependencies?
O3 Security finds GHSA-8p2f-fx4q-75cx across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
