Backstage is an open framework for building developer portals. Prior to 0.6.17, the @backstage/plugin-proxy-backend package is affected by improper input validation in proxy-backend. An authenticated Backstage user could craft a request URL that causes the proxy-backend to forward the request to a path outside the configured base path on the target server. This is limited to target servers already configured as proxy endpoints and requires Backstage authentication by default. This issue is fixed in version 0.6.17.

CVE-2026-927098.1 HIG—
——0Rsyslog is a rocket-fast system for log processing. From versions 1.15.0 to 8.2610.0, rsyslog's omfile dynaFile facility intentionally allows templates to generate flexible output paths. This supports valid deployments that route logs into different directories or use dynamically generated file names. A deployment becomes unsafe when a dynaFile template uses a value influenced by untrusted input as a path component without explicit secure-path handling. In that configuration, the rendered path can escape the operator's intended log directory. This is not limited to the RFC5424 HOSTNAME field. Any untrusted value that reaches a dynaFile path component can create the condition. At time of publication, there are no publicly available patches.1dCVE-2026-1152494.6 MED—
——0A flaw has been found in subhajitkhan online-clinic-management-system up to e9ee77a8827a1446220fa07ee693dc4d9a29a578. Impacted is an unknown function of the file patappointtime.php of the component Appointment Booking. This manipulation of the argument day/time/appdate causes improper input validation. The attack can be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.23hCVE-2026-1152075.5 MED—
——0A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user.22hCVE-2024-583967.5 HIG—
——0YouDataSum CPAS Audit Management System V4 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by manipulating the fileId parameter. Attackers can send GET requests to /cpasm4/plugInManController/downPlugs with ../ sequences in fileId to retrieve system files like /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-01-13.1dCVE-2022-510256.5 MED—
——0Penta Security WAPPLES 4.0.54.1, 5.0, and 6.0 contains a path traversal vulnerability that allows authenticated attackers to download arbitrary files via the name parameter of /webapi/file/transfer. Attackers can send GET requests with type=db_backup and ../ sequences in name to read files like /etc/passwd, and a hardcoded systemi account makes authentication effectively trivial. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.1dCVE-2022-510247.5 HIG—
——0Kavita 0.5.2 before 0.5.4.1 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by supplying '../' sequences in the filename parameter. Attackers can send GET requests to /api/image/cover-upload with filename values like ../appsettings.json to retrieve configuration files outside the temp directory. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.1d
