Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink entries are created without checking where targets point, path containment used a string prefix comparison, and file modes failed to remove setuid, setgid, or sticky bits. This issue is fixed in @xhmikosr/decompress versions 10.2.1 and 11.1.3.","state":0,"publishedAt":"2026-07-14T20:07:14.19+00:00","modifiedAt":"2026-07-15T13:26:56.864+00:00","affected":[{"ecosystem":"Vendor product","name":"decompress","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"XhmikosR\",\n                    \"product\": \"decompress\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 10.2.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.0.0, < 11.1.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/XhmikosR/decompress/security/advisories/GHSA-mp2f-45pm-3cg9","https://github.com/XhmikosR/decompress/commit/281cefa00cd4275c10479bc5f1abba6b14dee8bd","https://github.com/XhmikosR/decompress/commit/60b5299402e72b0b53ca2e55222e9a1ccb44afae","https://github.com/XhmikosR/decompress/commit/9fcda4b0a66ca22dc8d337f9b0e7c30293c5fb89","https://github.com/XhmikosR/decompress/commit/aca5aac415dc04a6fae5200e51368cff436a09dd","https://github.com/XhmikosR/decompress/releases/tag/v10.2.1","https://github.com/XhmikosR/decompress/releases/tag/v11.1.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53486","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53486","identifiers":["CVE-2026-53486"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
