Prior to versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13, pointerLock permission requests from some cross-origin iframes caused session.setPermissionRequestHandler() to receive the top-level frame's requestingUrl and isMainFrame values instead of those of the requesting frame. An application that embeds untrusted iframe content and grants pointer lock based on the requesting origin could therefore grant the permission under the top-level page's identity. Applications that deny pointerLock for untrusted embedded content are not affected. This issue is fixed in versions 42.11.9, 43.7.6, 44.5.0, and 45.0.0-alpha.13. ## CNA-Record (Kanon, cvelistV5) - CNA: **GitHub_M** - State: PUBLISHED - Stand: 2026-10-28 01:22:13 - CNA-CVSS: **5.4** (`CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L`) ## CISA-Anreicherung (vulnrichment/ADP) - CISA-SSVC (Coordinator, v2.0.3): - Exploitation: **none** - Automatable: **no** - Technical Impact: **partial** ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Gering | bad | | PR Privilegien | Keine | bad | | UI Interaktion | Erforderlich | good | | S Scope | Unverändert | good | | C Vertraulichkeit | Keine | good | | I Integrität | Gering | warn | | A Verfügbarkeit | Gering | warn | ## Schwachstellen-Klasse - **CWE-346** — Origin Validation Error The product does not properly verify that the source of data or communication is valid. ## Angriffsmuster (CAPEC) - [CAPEC-21 — Exploitation of Trusted Identifiers](https://capec.mitre.org/data/definitions/21.html) _(Severity: High)_ - [CAPEC-111 — JSON Hijacking (aka JavaScript Hijacking)](https://capec.mitre.org/data/definitions/111.html) _(Severity: High)_ - [CAPEC-141 — Cache Poisoning](https://capec.mitre.org/data/definitions/141.html) _(Severity: High)_ - [CAPEC-142 — DNS Cache Poisoning](https://capec.mitre.org/data/definitions/142.html) _(Severity: High)_ - [CAPEC-160 — Exploit Script-Based APIs](https://capec.mitre.org/data/definitions/160.html) _(Severity: Medium)_ - [CAPEC-384 — Application API Message Manipulation via Man-in-the-Middle](https://capec.mitre.org/data/definitions/384.html) _(Severity: Low)_ - [CAPEC-385 — Transaction or Event Tampering via Application API Manipulation](https://capec.mitre.org/data/definitions/385.html) _(Severity: Medium)_ - [CAPEC-386 — Application API Navigation Remapping](https://capec.mitre.org/data/definitions/386.html) _(Severity: Medium)_ ## ATT&CK-Techniken - [T1134 — Access Token Manipulation](https://attack.mitre.org/techniques/T1134/) - [T1528 — Steal Application Access Token](https://attack.mitre.org/techniques/T1528/) - [T1539 — Steal Web Session Cookie](https://attack.mitre.org/techniques/T1539/) - [T1557.002 — Adversary-in-the-Middle: ARP Cache Poisoning](https://attack.mitre.org/techniques/T1557/002/) - [T1584.002 — Compromise Infrastructure: DNS Server](https://attack.mitre.org/techniques/T1584/002/) ## Patch verfügbar (OSV) - d460d611a3d76010a3b0e02ca8739ed42ab591de (Commit) - 37e9cfaeefc2e45865e8c584a04de920f0c8e02e (Commit) ## Referenzen - - - - - - - - - - - - - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/sicherheitsluecken/cve-2026-113798/) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI WID (CSAF)_
