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.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

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
CVE-2024-52305 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 377,636 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.
Real-World Exposure

Description
Summary
A vulnerability exists in the Create User process, allowing the creation of a new admin account with an option to upload a profile image. An attacker can upload a malicious SVG file containing an embedded script. When the profile image is accessed, the embedded script executes, leading to the potential theft of session cookies.
Details
- Login as admin
- Go to Create User
- Fill up everything in the registration form then upload SVG image as a profile picture
- In SVG image, add script tag to prepare for XSS attack
- Complete the Create User process
- Right click at the image to obtain image URL address
- XSS triggered

Impact
The stored XSS can lead to session hijacking and privilege escalation, effectively bypassing any CSRF protections in place.

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 0.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-52305 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 CVE-2024-52305 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-52305. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-52305 in your dependencies?
O3 Security finds CVE-2024-52305 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
