CRITICALCodeIgniter4's ImageMagick Handler has Command Injection Vulnerability
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.

Description
Impact
This vulnerability affects applications that:
- Use the ImageMagick handler for image processing (
imagickas the image library) - AND either:
- Allow file uploads with user-controlled filenames and process uploaded images using the
resize()method - OR use the
text()method with user-controlled text content or options
- Allow file uploads with user-controlled filenames and process uploaded images using the
An attacker can:
- Upload a file with a malicious filename containing shell metacharacters that get executed when the image is processed
- OR provide malicious text content or options that get executed when adding text to images
Patches
Upgrade to v4.6.2 or later.
Workarounds
- Switch to the GD image handler (
gd, the default handler), which is not affected by either vulnerability - For file upload scenarios: Instead of using user-provided filenames, generate random names to eliminate the attack vector with
getRandomName()when using themove()method, or use thestore()method, which automatically generates safe filenames - For text operations: If you must use ImageMagick with user-controlled text, sanitize the input to only allow safe characters:
preg_replace('/[^a-zA-Z0-9\s.,!?-]/', '', $text)and validate/restrict text options

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for codeigniter4/framework. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update codeigniter4/framework to 4.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9952-gv64-x94c 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 pinpoints whether GHSA-9952-gv64-x94c is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-9952-gv64-x94c. 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-9952-gv64-x94c in your dependencies?
O3 detects GHSA-9952-gv64-x94c across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
