{"id":"CVE-2026-115796","kind":"vulnerability","aliases":["CVE-2026-115796"],"related":[],"title":"Tenda F6 router: web management interface allows cross-site request forgery","description":"A security flaw has been discovered in Tenda F6 12.02.01.73. This impacts an unknown function of the component Web Management Interface. Performing a manipulation results in cross-site request forgery. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks.","summary":"The web management interface of the Tenda F6 router (firmware 12.02.01.73) fails to protect against cross-site request forgery through an unknown function. A remote attacker who tricks a logged-in administrator into visiting a malicious page can make the device perform configuration changes.","severity":"medium","cvss":5.0,"epss":0.0023,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["infrastructure","router","self-hosted","tenda","tenda-f6"],"not_affected_if":["different-firmware"],"how_to_check":"- Log into the Tenda F6 web interface and note the firmware version shown in the status page; unknown whether the sources give a further check\n- Confirm whether the admin interface is reachable from the internet by checking the WAN-side management settings; unknown whether the sources name a specific setting","fix":"- unknown: the sources do not name a fixed firmware version or vendor patch\n- Restrict management access to the local network and disable remote web management until a fix is confirmed","status":"open","published_at":"2026-10-23T20:17:21+00:00","first_seen_at":"2026-10-23T21:57:34+00:00","triaged_at":"2026-10-25T04:29:21+00:00","updated_at":"2026-10-25T12:38:50+00:00","category":"infrastructure","confidence":0.5,"triage":{"at":"2026-10-25T04:29:21Z","model":"claude-haiku-5-5","output":{"fix":"- unknown: the sources do not name a fixed firmware version or vendor patch\n- Restrict management access to the local network and disable remote web management until a fix is confirmed","reach":"internet","title":"Tenda F6 router: web management interface allows cross-site request forgery","impact":"medium","summary":"The web management interface of the Tenda F6 router (firmware 12.02.01.73) fails to protect against cross-site request forgery through an unknown function.
