Technical description

Perry before 0.5.1159 contains a path traversal vulnerability that allows a malicious build server to write arbitrary content to any location writable by the running process by supplying unsanitized path components in the artifact_name field of ArtifactReady WebSocket messages. Attackers controlling the server URL can deliver traversal payloads through the artifact_name or download_path fields, causing the client to overwrite sensitive files or expose arbitrary local files to an attacker-accessible location.

CVE-2026-158018.0 HIG

—

———A vulnerability was found in CRI-O related to the container checkpoint and restore feature. When CRI-O is configured to restore containers from checkpoint archives, insufficient validation of restore metadata may allow a user with sufficient privileges to perform unintended operations on the host filesystem. Successful exploitation requires that container checkpoint and restore functionality is enabled, which is not the default configuration. An attacker must also be able to trigger restoration of a container from untrusted checkpoint content.6h CVE-2026-941855.5 MED

———nvm resolves a requested version or alias by treating it as a filename under $NVM_DIR/alias. Before 0.40.8, nvm_alias() concatenated the requested name onto that directory and read the result with no containment check, so a name containing a `..` component escaped the alias directory; under the default layout an alias such as `../../.npmrc` resolves to a file in the user's home directory. nvm_print_alias_file() then emits every non-comment, non-empty line of whatever was opened. A version string taken from an untrusted .nvmrc reaches this path, so a developer who runs `nvm use`, `nvm install`, or `nvm which` inside an attacker-supplied repository discloses the first non-comment line of an arbitrary file readable by that user, in the resulting "is not yet installed" error message. A user-supplied `nvm alias <traversing-name>` discloses every non-comment line of the target file. There is no integrity or availability impact, and no command execution on this path.12h CVE-2026-940494.3 MED

———A flaw has been found in 06ketan slideshot up to 4.4.0. This impacts the function render_slides of the file packages/cli/src/renderer.ts. This manipulation of the argument htmlPath causes path traversal. The attack is possible to be carried out 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.2h CVE-2026-940464.3 MED

——0A weakness has been identified in 0215AndrewFeng ACE-MCP up to 4.10.8. The affected element is the function get_file_snippet of the file getFileSnippet.ts of the component MCP Tool. Executing a manipulation of the argument projectRootPath/filePath can lead to path traversal. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. isPathInsideProjectRoot only blocks filePath escaping the attacker-chosen projectRootPath; the root itself is untrusted client input - set projectRootPath=/etc, filePath=hosts and the guard passes. The project was informed of the problem early through an issue report but has not responded yet.2h CVE-2026-940447.3 HIG

——0A vulnerability was identified in 03-lovepreetSingh MCP up to f95d035c5317fad81af9828286631053ccb23546. This issue affects the function create_file of the file app/api/mcp/route.ts. Such manipulation of the argument filePath/content leads to path traversal. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.2h CVE-2026-940374.3 MED

——0A weakness has been identified in 00Kisumi00 mcp-file-analyzer up to 84740852f0cf0cf5db4781b1ca6d7c6a6d210405. This affects the function ControlFlowNode of the file main.py of the component analyze_csv_data MCP tool. This manipulation of the argument filename causes path traversal. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.2h
