In versions 3.0.0 and 3.0.1, a path traversal vulnerability in `brut/androlib/res/decoder/ResFileDecoder.java` allows a maliciously crafted APK to write arbitrary files to the filesystem during standard decoding (`apktool d`). This is a security regression introduced in commit e10a045 (PR #4041, December 12, 2025), which removed the `BrutIO.sanitizePath()` call that previously prevented path traversal in resource file output paths. An attacker can embed `../` sequences in the `resources.arsc` Type String Pool to escape the output directory and write files to arbitrary locations, including `~/.ssh/config`, `~/.bashrc`, or Windows Startup folders, escalating to RCE. The fix in version 3.0.2 re-introduces `BrutIO.sanitizePath()` in `ResFileDecoder.java` before file write operations.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-39973","reference_id":"","reference_type":"","scores":[{"value":"6e-05","scoring_system":"epss","scoring_elements":"0.00326","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-39973"},{"reference_url":"https://github.com/iBotPeaches/Apktool","reference_id":"","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/iBotPeaches/Apktool"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39973","reference_id":"","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39973"},{"reference_url":"https://github.com/iBotPeaches/Apktool/pull/4041","reference_id":"4041","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:T/P:M/B:A/M:M/D:T/2026-04-21T13:33:04Z/"}],"url":"https://github.com/iBotPeaches/Apktool/pull/4041"},{"reference_url":"https://github.com/iBotPeaches/Apktool/commit/e10a0450c7afcd9462c0b76bcbff0e7428b92bdd#diff-cd531ebe1014bfd18185bf21585ca5cdb16fbcb07703ebc47949a1b4e4e36bc3","reference_id":"e10a0450c7afcd9462c0b76bcbff0e7428b92bdd#diff-cd531ebe1014bfd18185bf21585ca5cdb16fbcb07703ebc47949a1b4e4e36bc3","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:T/P:M/B:A/M:M/D:T/2026-04-21T13:33:04Z/"}],"url":"https://github.com/iBotPeaches/Apktool/commit/e10a0450c7afcd9462c0b76bcbff0e7428b92bdd#diff-cd531ebe1014bfd18185bf21585ca5cdb16fbcb07703ebc47949a1b4e4e36bc3"},{"reference_url":"https://github.com/advisories/GHSA-m8mh-x359-vm8m","reference_id":"GHSA-m8mh-x359-vm8m","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-m8mh-x359-vm8m"},{"reference_url":"https://github.com/iBotPeaches/Apktool/security/advisories/GHSA-m8mh-x359-vm8m","reference_id":"GHSA-m8mh-x359-vm8m","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:T/P:M/B:A/M:M/D:T/2026-04-21T13:33:04Z/"}],"url":"https://github.com/iBotPeaches/Apktool/security/advisories/GHSA-m8mh-x359-vm8m"},{"reference_url":"https://github.com/iBotPeaches/Apktool/releases/tag/v3.0.2","reference_id":"v3.0.2","reference_type":"","scores":[{"value":"7.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:T/P:M/B:A/M:M/D:T/2026-04-21T13:33:04Z/"}],"url":"https://github.com/iBotPeaches/Apktool/releases/tag/v3.0.2"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/374211?format=json","purl":"pkg:maven/org.apktool/apktool-lib@3.0.2","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.apktool/apktool-lib@3.0.2"}],"aliases":["CVE-2026-39973","GHSA-m8mh-x359-vm8m"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-ufs4-dtuu-8feg"}],"fixing_vulnerabilities":[],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.apktool/apktool-lib@3.0.0"}
