Vulnerability database
Every flaw the U.S. government’s cybersecurity agency (CISA) has confirmed attackers are using, plus the new WordPress plugin and theme bugs published each day, sorted by what they mean for a small business. We refresh it twice a day. If you see something your website or office runs, tell us.

Aug 13, 2025This vulnerability exists in ZKTeco WL20 due to storage of Wi-Fi credentials, configuration data and system data in plaintext within the device firmware.CVE-2025-55280 · Other software · ZKTeco Co · reported by vdisclose@cert-in.org.inMedium 5.2
This vulnerability exists in ZKTeco WL20 due to storage of Wi-Fi credentials, configuration data and system data in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the plaintext sensitive data stored in the targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized network access, retrieve and manipulate data on the targeted device.

Aug 13, 2025This vulnerability exists in ZKTeco WL20 due to hard-coded private key stored in plaintext within the device firmware.CVE-2025-55279 · Other software · ZKTeco Co · reported by vdisclose@cert-in.org.inMedium 6.9
This vulnerability exists in ZKTeco WL20 due to hard-coded private key stored in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and analyzing the binary data to retrieve private key stored in the firmware of the targeted device. Successful exploitation of this vulnerability could allow the attacker to perform unauthorized decryption of sensitive data and Man-in-the-Middle (MitM) attacks on the targeted device.

Aug 13, 2025This vulnerability exists in ZKTeco WL20 due to hard-coded MQTT credentials and endpoints stored in plaintext within the device firmware.CVE-2025-54465 · Other software · ZKTeco Co · reported by vdisclose@cert-in.org.inMedium 6.8
This vulnerability exists in ZKTeco WL20 due to hard-coded MQTT credentials and endpoints stored in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and analyzing the binary data to retrieve the hard-coded MQTT credentials and endpoints from the targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the MQTT broker and manipulate the communications of the targeted device.

Aug 13, 2025This vulnerability exists in ZKTeco WL20 due to storage of admin and user credentials without encryption in the device firmware.CVE-2025-54464 · Other software · ZKTeco Co · reported by vdisclose@cert-in.org.inHigh 7
This vulnerability exists in ZKTeco WL20 due to storage of admin and user credentials without encryption in the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the unencrypted credentials stored in the firmware of targeted device.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
