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-2026-3780

Publication date:
01/04/2026
The application's installer runs with elevated privileges but resolves system executables and DLLs using untrusted search paths that can include user-writable directories, allowing a local attacker to place malicious binaries with the same names and have them loaded or executed instead of the legitimate system files, resulting in local privilege escalation.

CVE-2026-3779

Publication date:
01/04/2026
The application's list box calculate array logic keeps stale references to page or form objects after they are deleted or re-created, which allows crafted documents to trigger a use-after-free when the calculation runs and can potentially lead to arbitrary code execution.

CVE-2026-4947

Publication date:
01/04/2026
Addressed a potential insecure direct object reference (IDOR) vulnerability in the signing invitation acceptance process. Under certain conditions, this issue could have allowed an attacker to access or modify unauthorized resources by manipulating user-supplied object identifiers, potentially leading to forged signatures and compromising the integrity and authenticity of documents undergoing the signing process. The issue was caused by insufficient authorization validation on referenced resources during request processing.

CVE-2026-5249

Publication date:
01/04/2026
A vulnerability was found in gougucms 4.08.18. This impacts an unknown function of the file \gougucms-master\app\admin\view\user\record.html of the component Record Endpoint. Performing a manipulation of the argument value.content results in cross site scripting. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
Severity CVSS v4.0: LOW

CVE-2026-3774

Publication date:
01/04/2026
The application allows PDF JavaScript and document/print actions (such as WillPrint/DidPrint) to update form fields, annotations, or optional content groups (OCGs) immediately before or after redaction, encryption, or printing. These script‑driven updates are not fully covered by the existing redaction, encryption, and printing logic, which, under specific document structures and user workflows, may cause a small amount of sensitive content to remain unremoved or unencrypted as expected, or result in printed output that slightly differs from what was reviewed on screen.

CVE-2026-3778

Publication date:
01/04/2026
The application does not detect or guard against cyclic PDF object references while handling JavaScript in PDF. When pages and annotations are crafted that reference each other in a loop, passing the document to APIs (e.g., SOAP) that perform deep traversal can cause uncontrolled recursion, stack exhaustion, and application crashes.

CVE-2026-3777

Publication date:
01/04/2026
The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.

CVE-2026-3776

Publication date:
01/04/2026
The application does not validate the presence of required appearance (AP) data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service.

CVE-2026-3775

Publication date:
01/04/2026
The application's update service, when checking for updates, loads certain system libraries from a search path that includes directories writable by low‑privileged users and is not strictly restricted to trusted system locations. Because these libraries may be resolved and loaded from user‑writable locations, a local attacker can place a malicious library there and have it loaded with SYSTEM privileges, resulting in local privilege escalation and arbitrary code execution.

CVE-2026-35057

Publication date:
01/04/2026
XenForo before 2.3.10 and before 2.2.19 is vulnerable to stored cross-site scripting (XSS) in structured text mentions, primarily affecting legacy profile post content. An attacker can inject malicious scripts through crafted mentions that are stored and executed when other users view the content.

CVE-2026-35054

Publication date:
01/04/2026
XenForo before 2.3.9 is vulnerable to stored cross-site scripting (XSS) related to BB code rendering. An attacker can inject malicious scripts through BB code that are stored and executed when other users view the content.

CVE-2026-35055

Publication date:
01/04/2026
