Which packages are affected by GHSA-j2hp-6m75-v4j4?

GHSA-j2hp-6m75-v4j4 affects the following packages: github.com/imgproxy/imgproxy (Go). Ecosystems affected: Go.

How do I fix GHSA-j2hp-6m75-v4j4?

Update github.com/imgproxy/imgproxy to 3.27.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j2hp-6m75-v4j4 is resolved across your whole dependency graph.

How do I detect GHSA-j2hp-6m75-v4j4 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/imgproxy/imgproxy. 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.

How do I mitigate GHSA-j2hp-6m75-v4j4 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-j2hp-6m75-v4j4?

O3 pinpoints whether GHSA-j2hp-6m75-v4j4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-j2hp-6m75-v4j4 actively exploited in the wild?

No public exploit code has been indexed for GHSA-j2hp-6m75-v4j4 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 GHSA-j2hp-6m75-v4j4?

GHSA-j2hp-6m75-v4j4 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 53th 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 GHSA-j2hp-6m75-v4j4?

GHSA-j2hp-6m75-v4j4 is classified as Server-Side Request Forgery (SSRF) (CWE-918). 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.

Is there exploit tooling available for GHSA-j2hp-6m75-v4j4?

A Nuclei detection template exists for GHSA-j2hp-6m75-v4j4, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-j2hp-6m75-v4j4 published, and has it been updated?

GHSA-j2hp-6m75-v4j4 was published on January 27, 2025 and was last updated on January 28, 2025. 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 Go packages — download data is not available via public APIs for these ecosystems.

Description

Summary

Imgproxy does not block the 0.0.0.0 address, even with IMGPROXY_ALLOW_LOOPBACK_SOURCE_ADDRESSES set to false. This can expose services on the local host.

Details

imgproxy protects against SSRF against a loopback address with the following check (source):

if !config.AllowLoopbackSourceAddresses && ip.IsLoopback() {
	return ErrSourceAddressNotAllowed
}

This check is insufficient to prevent accessing services on the local host, as services may receive traffic on 0.0.0.0. Go's IsLoopback (source) strictly follows the definition of loopback IPs beginning with 127. 0.0.0.0 is not blocked.
