GHSA-7vpr-3ppw-qrpj is a high-severity (CVSS 8.8) vulnerability in Imageflow.AllPlatforms. A fix is available for Imageflow.AllPlatforms — see the affected versions and patch details below.
Imageflow affected by libwebp zero-day and should not be used with malicious source images.

Description
Impact
This vulnerability affects deployments of Imageflow that involve decoding or processing malicious source .webp files. If you only process your own trusted files, this should not affect you (but you should update anyway).
Imageflow relies on Google's [libwebp] library to decode .webp images, and is affected by the recent zero-day out-of-bounds write vulnerability CVE-2023-4863 and https://github.com/advisories/GHSA-j7hp-h8jx-5ppr. The libwebp vulnerability also affects Chrome, Android, macOS, and other consumers of the library).
libwebp patched the vulnerability and released 1.3.2
This was patched in libwebp-sys in 0.9.3 and 0.9.4
Imageflow v2.0.0-preview8 uses the patched version of libwebp as well as updated versions of all dependencies.
Note: preview 8 requires libc 2.31 or higher on linux and macOS 11 or higher. These restrictions are due to the oldest supported versions of those platforms (which is reflected on Github Actions).
Patches
Imageflow v2.0.0-preview8 use the patched version (v1.3.2) of libwebp and libwebp-sys 0.9.4. Imageflow.AllPlatforms 0.10.2 is patched Imageflow.Server v0.8.2 is patched ImageResizer.Plugins.Imageflow 5.0.12 is patched
Workarounds
Disable webp decoding using EnabledCodecs::disable_decoder(NamedDecoders::WebPDecoder) if using the Rust API.
Only files that meet the following criteria will be passed to libwebp:
bytes.starts_with(b"RIFF") && bytes[8..12].starts_with(b"WEBP")
You can utilize matching logic to block webp inputs in your language of choice.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Imageflow.AllPlatforms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update Imageflow.AllPlatforms to 0.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7vpr-3ppw-qrpj 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 GHSA-7vpr-3ppw-qrpj can be triaged on real exposure rather than presence alone.
Tailored to GHSA-7vpr-3ppw-qrpj. 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-7vpr-3ppw-qrpj in your dependencies?
O3 Security finds GHSA-7vpr-3ppw-qrpj across NuGet dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
