Detailsinfo

A vulnerability classified as critical was found in Image::WebP up to 0.2. Affected by this vulnerability is an unknown code block. The manipulation with an unknown input leads to a insufficient isolation of system-dependent functions vulnerability. The CWE definition for the vulnerability is CWE-1100. The product or code does not isolate system-dependent functionality into separate standalone modules. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Image::WebP versions through 0.2 for Perl bundle a vulnerable version of libwebp. Image::WebP does not link to the system libwebp. Instead, it uses a bundled copy of libwebp 0.3.0 (released 2013-03-20). That version has multiple known vulnerabilities, including CVE-2023-4863. Any caller that decodes an untrusted WebP image reaches the bundled decoder. Because the library is compiled into the module, upgrading the system libwebp does not remediate this.

The advisory is shared at metacpan.org. This vulnerability is known as CVE-2026-58586 since 07/01/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/24/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
