How severe is CVE-2025-54418?

CVE-2025-54418 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2025-54418?

CVE-2025-54418 affects the following packages: codeigniter4/framework (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2025-54418?

Update codeigniter4/framework to 4.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-54418 is resolved across your whole dependency graph.

How do I detect CVE-2025-54418 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for codeigniter4/framework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-54418 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2025-54418 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-54418 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-54418?

CVE-2025-54418 has an EPSS (Exploit Prediction Scoring System) score of 1.5%, placing it in the 74th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-54418?

CVE-2025-54418 is classified as OS Command Injection (CWE-78). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-54418 published, and has it been updated?

CVE-2025-54418 was published on July 28, 2025 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Impact

This vulnerability affects applications that:

Use the ImageMagick handler for image processing (imagick as 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

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 the move() method, or use the store() 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
