CVE ID: CVE-2026-111946 Distribution: Plack-Middleware-ETag Versions: from 0.04 before 0.06 MetaCPAN: https://metacpan.org/dist/Plack-Middleware-ETag VCS Repo: https://github.com/robrwo/perl-Plack-Middleware-ETag Plack::Middleware::ETag versions from 0.04 before 0.06 for Perl disclose file inode numbers in the default ETag header Description ----------- Plack::Middleware::ETag versions from 0.04 before 0.06 for Perl disclose file inode numbers in the default ETag header. When the response body is a filehandle and the file_etag option is not set, the ETag is built from the file's inode number, modification time and size. Clients receiving affected responses may use the disclosed inode numbers to aid backend fingerprinting and correlation of files served through different URLs. Problem types ------------- - CWE-497 Exposure of Sensitive System Information to an Unauthorized Control Sphere Workarounds ----------- For deployments that cannot upgrade to 0.06, where the file_etag option is set, remove the use of "inode". If the file_etag option is not specified, change it to ["mtime", "size"]. Solutions --------- Upgrade to Plack-Middleware-ETag 0.06 or later. Where the file_etag option is set, remove the use of "inode".
