An attacker can publish a crafted image to registries such as DockerHub, and once a user loads it, the attacker can write arbitrary content to any host path, which can lead to remote code execution on the host. The flaw sits in extract_layer_tarball_streaming and apply_oci_layer in boxlite/src/images/archive/tar.rs, and ensure_parent_dirs deliberately preserves symlinks that escape the extraction root.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-f396-4rp4-7v2j","publishedAt":"2026-05-21T21:54:15.000Z","cveId":"CVE-2026-46703","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["github.com/boxlite-ai/boxlite/sdks/go@< 0.9.0 (fixed: 0.9.0)","@boxlite-ai/boxlite@< 0.9.0 (fixed: 0.9.0)","boxlite@< 0.9.0 (fixed: 0.9.0)","boxlite-cli@< 0.9.0 (fixed: 0.9.0)","boxlite@< 0.9.0 (fixed: 0.9.0)"],"affectedPackageNames":["github.com/boxlite-ai/boxlite/sdks/go","@boxlite-ai/boxlite","boxlite","boxlite-cli"],"affectedPackageRefs":["pypi:boxlite","cargo:boxlite-cli","cargo:boxlite","npm:@boxlite-ai/boxlite","go:github.com/boxlite-ai/boxlite/sdks/go"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["Boxlite","DockerHub","OCI container images"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00777,"epssCheckedAt":"2026-10-14T06:09:07.401Z","kevDateAdded":null,"advisoryAliases":["GHSA-f396-4rp4-7v2j"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-05-21T21:54:15.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"inference","llmSpecific":false,"classifierConfidence":0.6,"researchCategory":null,"atlasIds":["AML.T0010"]}}
