Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE  (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2026-36613

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 with firmware AC12G(EU)_V1_200909 returns 128 bytes of uninitialized internal buffer contents when receiving HTTP POST requests to undefined paths, exposing server state to unauthenticated adjacent network attackers.

CVE-2026-36615

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 with firmware AC12G(EU)_V1_200909 exposes an undocumented /agileconfigreset endpoint that returns internal buffer contents to unauthenticated attackers on the adjacent network.

CVE-2026-36609

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 uses a static authentication nonce that does not change between requests from the same source IP. Combined with the predictable XOR-based password encoding (securityEncode function), this allows an attacker to reverse captured authentication tokens to recover the plaintext password.

CVE-2026-36611

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 with firmware AC12G(EU)_V1_200909 returns 128 bytes of uninitialized buffer when receiving POST requests without SOAPAction header on UPnP port 1900, exposing internal memory to unauthenticated adjacent network attackers.

CVE-2026-36610

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 with firmware AC12G(EU)_V1_200909 transmits DDNS credentials over plaintext HTTP with only Base64 encoding. The firmware contains no TLS implementation, allowing man-in-the-middle interception of DDNS service credentials.

CVE-2026-36602

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 discloses kernel memory layout via the UPnP GetStatusInfo action. An unauthenticated attacker on the adjacent network can obtain a raw MIPS KSEG0 kernel pointer, revealing kernel memory layout and aiding further exploitation.

CVE-2026-36603

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 exposes 15 of 18 UPnP IGD actions without authentication on port 1900, including AddPortMapping and GetExternalIPAddress. UPnP is enabled by default through the admin interface, allowing any unauthenticated LAN device to create arbitrary port forwarding rules and access WAN traffic statistics.

CVE-2026-36605

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 is vulnerable to a HTTP denial of service via a low number of crafted incomplete HTTP requests, causing a persistent crash that requires physical power cycling to recover.

CVE-2026-36606

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 encrypts configuration backups with a hardcoded DES key using single DES in ECB mode. An attacker who obtains a backup file can decrypt it to recover all stored credentials including admin password, WiFi PSK, and DDNS credentials.

CVE-2026-36607

Publication date:
03/06/2026
Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 allows unauthenticated brute-force attacks via the TDDP password change endpoint (code=10), which lacks the rate limiting applied to the login endpoint (code=7). An attacker on the adjacent network can attempt unlimited passwords without triggering account lockout.
