Which packages are affected by GHSA-g85r-6x2q-45w7?

GHSA-g85r-6x2q-45w7 affects the following packages: SixLabors.ImageSharp (NuGet), SixLabors.ImageSharp (NuGet). Ecosystems affected: NuGet.

How do I fix GHSA-g85r-6x2q-45w7?

Update SixLabors.ImageSharp to 2.1.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g85r-6x2q-45w7 is resolved across your whole dependency graph.

How do I detect GHSA-g85r-6x2q-45w7 in my NuGet dependencies?

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

How do I mitigate GHSA-g85r-6x2q-45w7 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-g85r-6x2q-45w7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-g85r-6x2q-45w7 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-g85r-6x2q-45w7?

GHSA-g85r-6x2q-45w7 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 51th 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-g85r-6x2q-45w7?

Description

Impact

A vulnerability discovered in the ImageSharp library, where the processing of specially crafted files can lead to excessive memory usage in image decoders. The vulnerability is triggered when ImageSharp attempts to process image files that are designed to exploit this flaw.

This flaw can be exploited to cause a denial of service (DoS) by depleting process memory, thereby affecting applications and services that rely on ImageSharp for image processing tasks. Users and administrators are advised to update to the latest version of ImageSharp that addresses this vulnerability to mitigate the risk of exploitation.

Patches

The problem has been patched. All users are advised to upgrade to v3.1.4 or v2.1.8.

Workarounds

Before calling Image.Decode(Async), use Image.Identify to determine the image dimensions in order to enforce a limit.
