Descripción técnica

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link("victim.secret", "<extract_base>/payload.tar.gz/evil_cwd_link") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname="victim.secret" with io.deis.oras.content.unpack: "true", which can expose or tamper with files such as .env, .git/config, .aws/credentials, and ~/.ssh/config. This issue is fixed in version 2.6.2.

——0ArcadeDB is a Multi-Model DBMS. Prior to 26.6.1, the IMPORT DATABASE statement in engine/src/main/java/com/arcadedb/query/sql/parser/ImportDatabaseStatement.java did not require administrative privileges and passed its source to integration/src/main/java/com/arcadedb/integration/importer/SourceDiscovery.java without validation. An authenticated user with SQL command access through /api/v1/command or /api/v1/query can supply HTTP or HTTPS destinations to make server-side requests to internal services, or file:// paths to read files accessible to the server process and ingest the results as queryable records. The XML importer also permits DTD processing and external entities, enabling entity expansion. The root-only /api/v1/server administration endpoint is not affected. The fix requires updateSecurity permission, blocks local-network import destinations by default through arcadedb.server.security.importBlockLocalNetworks, supports the arcadedb.server.security.importAllowedLocalPaths file allow-list, and disables XML DTD processing and external entities. This issue is fixed in version 26.6.1.23h CVE-2026-500245.3 MED

——0GitHacker is a tool that restores Git repositories from exposed .git directories. In 1.1.7 and earlier, add_head_file_tasks parses an attacker-controlled ref path from .git/HEAD and joins unvalidated path segments onto temp_dst/.git/logs/, allowing a malicious server to make GitHacker read an arbitrary local file when a victim runs the tool against the server's URL. add_hashes_parsed then scans the file for 40-character hexadecimal substrings and requests each match through .git/objects using the first two characters and remaining characters as path components, creating an attacker-observable existence oracle and disclosing matching hexadecimal fragments. Complete file contents are not returned, and the add_folder and add_task write path in shipped version 1.1.7 does not permit an escape. This issue is fixed in repository version 1.1.9.23h CVE-2026-472154.8 MED

——0SingularityCE and SingularityPRO are open source container platforms. Prior to SingularityCE 4.4.2 and SingularityPRO 4.3.9 and 4.1.14, incorrect path-string matching in the singularity.conf limit container paths directive allows a container in a sibling directory such as /data/safe-but-unsafe to be run when /data/safe is allowed under setuid mode. This permits a user to run a container from outside the administrator's configured path allowlist. Installations that do not use limit container paths are not affected. This issue is fixed in SingularityCE 4.4.2 and SingularityPRO 4.3.9 and 4.1.14.20h CVE-2026-77179—

——0On macOS, the virtio-fs host server used by Docker Sandboxes improperly follows symlinks when reopening an unlinked file from a stored path. A malicious guest can replace a parent directory with a symlink, escape the shared workspace, and read or modify arbitrary host files as the VMM user, potentially achieving host code execution.17h CVE-2026-917718.8 ALT

——16Weights & Biases wandb before 0.29.0 fails to validate the file name from server responses in the File.download function, allowing path traversal attacks. Attackers controlling the backend can supply file names with directory traversal sequences to write files outside the intended download directory, potentially enabling code execution through modification of shell startup files or Python import paths.2d CVE-2026-917518.3 ALT

——8Flextype CMS through 1.0.0-alpha.3 fails to properly validate id and new_id parameters in the Entries REST API, allowing API token holders to read, create, or overwrite files outside the entries directory. Attackers can use traversal sequences in API requests to escape the project entries directory and manipulate arbitrary files and directories on the filesystem.20h
