TP-Link: security record
CISA's Known Exploited Vulnerabilities catalog lists 6 flaws in TP-Link routers and network gear that attackers have exploited in the wild, added between 25 March 2022 and 3 September 2025.
What this list means
CISA adds a flaw to its Known Exploited Vulnerabilities catalog when there is reliable evidence that attackers have used it in the wild and clear steps exist to fix or reduce it. A listed flaw usually has a patch or workaround from the maker. Some older devices are no longer supported and will not be fixed. If you own an affected model, check the maker's notice, update the firmware or replace the device if it is out of support.
TP-Link TL-WR841N Authentication Bypass by Spoofing Vulnerability
TP-Link TL-WR841N contains an authentication bypass by spoofing vulnerability within the httpd service, which listens on TCP port 80 by default, leading to the disclose of stored credentials. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
TP-Link Archer C7(EU) and TL-WR841N/ND(MS) OS Command Injection Vulnerability
TP-Link Archer C7(EU) and TL-WR841N/ND(MS) contain an OS command injection vulnerability that exists in the Parental Control page. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
TP-link TL-WA855RE Missing Authentication for Critical Function Vulnerability
TP-link TL-WA855RE contains a missing authentication for critical function vulnerability. This vulnerability could allow an unauthenticated attacker (on the same network) to submit a TDDP_RESET POST request for a factory reset and reboot. The attacker can then obtain incorrect access control by setting a new administrative password. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
TP-Link Multiple Routers Command Injection Vulnerability
TP-Link TL-WR940N V2/V4, TL-WR841N V8/V10, and TL-WR740N V1/V2 contain a command injection vulnerability via the component /userRpm/WlanNetworkRpm. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
TP-Link Archer AX-21 Command Injection Vulnerability
TP-Link Archer AX-21 contains a command injection vulnerability that allows for remote code execution.
TP-Link Multiple Archer Devices Directory Traversal Vulnerability
Directory traversal vulnerability in multiple TP-Link Archer devices allows remote attackers to read arbitrary files via a .. (dot dot) in the PATH_INFO to login/.
A listing shows that a flaw was exploited, not how a maker compares overall. Makers with many devices in use tend to appear more often. Check the maker's own notice for the models and firmware versions affected.
