Technical description

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, "\", "/"), which turns a POSIX filename such as ..\..\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.

——0Shamefile is a linter for undocumented linter warnings. Prior to version 0.1.7, a path traversal vulnerability in `shame next` allows an attacker-controlled `shamefile.yaml` to disclose contents of files outside the repository, one line at a time, to the terminal of a user who runs the command. See patch commit for technical details. The issue is fixed in 0.1.7. Upgrade to either 0.1.7 or later versions to incorporate the patch. As a workaround, do not run `shame next` against untrusted `shamefile.yaml`. Use `shame me --dry-run` for CI validation.15h CVE-2026-566237.1 HIG

——0Path traversal on Windows in Apache MINA SSHD component sshd-git. Apache MINA SSHD is a Java library for client-side and server-side SSH. A git server implemented with Apache MINA SSHD component sshd-git and running on Windows could allow an authenticated remote user access to git repositories outside of the configured server-side root directory. The path validation applied for CVE-2026-48827 in Apache MINA SSHD 2.18.0 and 3.0.0-M4 was partly ineffective for Servers running on Windows. Applications are affected if they use org.apache.sshd:sshd-git to implement a git server and run on Windows. Applications not using sshd-git or not running on Windows are not affected. Users are advised to upgrade affected applications to Apache MINA SSHD 2.19.0, which fixes the issue. The issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M4 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git and run on Windows. Upgrade affected applications to 3.0.0-M5.16h CVE-2026-564527.5 HIG

——0Path traversal in the sshd-scp component of Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH. The implementation of receiving files or directories via SCP did not validate filenames in SCP "C" or "D" commands. A malicious sender could send filenames containing paths, resulting in files to be written in attacker-controlled places. The issue affects only * applications that use no longer supported Apache MINA SSHD versions < 2.0.0 and use the SCP functions to receive files, * or applications using sshd-scp in Apache MINA SSHD >= 2.0.0 to receive files. Applications using Apache MINA SSHD >= 2.0.0 not using sshd-scp are not affected. The issue is fixed in Apache MINA 2.19.0 and 3.0.0-M5. Affected applications are advised to upgrade to these versions.14h CVE-2026-535944.9 MED

——0FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. FreeScout's `Manage -> Logs -> App Logs` feature uses the bundled `rap2hpoutre/laravel-log-viewer` override to decrypt a user-supplied file identifier and then pass the resolved path to Laravel's download response. Prior to version 1.8.224, the path resolution logic accepts any existing absolute path before applying the intended `storage/logs` restriction. As a result, an attacker who can access the App Logs route and forge a valid Laravel-encrypted `dl` parameter can download arbitrary server-local files readable by the PHP process, not just log files. Version 1.8.224 contains a fix.16h CVE-2026-60027—

——0Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, `EnvironmentManager.listBackups()` reads each backup's `_manifest.json` and trusts the manifest's `path` field. `EnvironmentManager.pruneBackups()` later passes that trusted `entry.path` directly to `rmSync(entry.path, { recursive: true, force: true })`. An attacker who can place or modify a manifest inside `data/<env>/.backups/<name>/_manifest.json` can cause `network-ai env backup prune --env <env> --keep <n>` or any code path invoking `pruneBackups()` to recursively delete an arbitrary path accessible to the Network-AI process user. This is fixed in v5.12.2. `pruneBackups()` no longer passes `entry.path` from the on-disk manifest to `rmSync`. The deletion path is recomputed from a format-validated `entry.backupId`, and a `dirname` containment check confines deletion to exactly one level under the backups directory. A poisoned manifest (e.g. `"path": "/"`) is now inert.18h
