CVE-2026-114112Published

Sharp before 0.35.4 RCE via bundled libheif AVIF decoding

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Sharp before 0.35.4 bundles a vulnerable libheif dependency that allows attackers to achieve possible remote code execution on glibc-based Linux by supplying crafted images. Attackers can submit malicious AVIF/HEIF input to applications processing untrusted images with sharp, triggering libheif decoding flaws to execute code.

### Impact A number of vulnerabilities, two rated as "Critical" severity using CVSSv3, have been discovered and fixed in the upstream libheif dependency. These can lead to possible remote code execution (RCE) on glibc-based Linux when run under certain conditions. The attack vector for these claims to be "network" however sharp does not provide any networking features so this vulnerability is down-rated to a "High" severity using CVSSv4 but please note its Subsequent System Impact. Those processing untrusted input with versions of sharp prior to 0.35.4 are affected. ### Patches #### Using prebuilt binaries provided by sharp? Most people rely on the prebuilt binaries provided by sharp. Please upgrade sharp to the latest version, currently 0.35.4, which provides libheif 1.23.2. #### Using a globally-installed libheif? Please ensure you are using the latest libheif 1.23.2. ### Workarounds Add the following to your code to prevent sharp from decoding AVIF images. ```js sharp.block({ operation: ["VipsForeignLoadHeif"] }); ``` Ensure you are using a `node` executable binary compiled as a Position Independent Executable (PIE). Most Linux package managers already do this for protection against RCE however be warned that the "official" Node.js binaries do not. ### References - [CVE-2026-84383](https://github.com/strukturag/libheif/security/advisories/GHSA-g89c-p67h-r497) - https://github.com/strukturag/libheif/security/advisories/GHSA-2jg2-4ch7-h545
