Technical description

A vulnerability in Cisco Expressway Series could allow an unauthenticated, remote attacker to obtain sensitive information from an affected device. This vulnerability is due to insufficient authorization checks of HTTP requests during Mobile and Remote Access (MRA) provisioning. An attacker could exploit this vulnerability by submitting a crafted URL request to an affected device. A successful exploit could allow the attacker to access sensitive information that they would otherwise not have authorization to access. Note: Cisco Expressway Series refers to Cisco Expressway Core (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices.

CVE-2026-1110797.4 HIG

———A flaw was found in Goose. When the terminal integration feature is enabled, the application captures shell command history and sends it verbatim without sanitization to configured Large Language Model (LLM) provider endpoints during queries. If a user enters sensitive data—such as API tokens, passwords, or environment variables containing secrets—in the terminal, this unredacted information is transmitted across trust boundaries. This can lead to sensitive information disclosure, exposing confidential credentials to external service providers and logs.2h CVE-2026-1080897.5 HIG

——12** UNSUPPORTED WHEN ASSIGNED ** Exposure of sensitive system information to an unauthorized control sphere vulnerability in Apache Cocoon. An unauthenticated user could gain access to diagnostic interfaces, including triggering of cache, exposure of (verbose) debug logging and profile information. This issue affects Apache Cocoon: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.2d CVE-2026-111946—

——2Plack::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.2d CVE-2026-1104664.3 MED
