CVE-2026-8993
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedD.Launcher 2 component of Slovak eID client ecosystem contains Improper URL Handler Processing vulnerability. Application registers multiple custom URL handlers that could be exploited to initiate full NTLM autentication or SMB connection to attacker infrastructure and to conduct SSRF (Server Side Request Forgery) attacks. User interaction is required as potential victim needs to open a specially crafted URL.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceD.Launcher 2, a component of the Slovak eID client ecosystem, contains improper URL handler processing. The application registers multiple custom URL handlers that fail to properly validate incoming URLs, enabling attackers to trigger NTLM authentication or SMB connections to attacker-controlled infrastructure and conduct SSRF attacks. Exploitation requires a victim to open a specially crafted URL.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if D.Launcher 2 is installedSearch for D.Launcher 2 in installed programs (Windows: Programs and Features, or check Program Files directories for a D.Launcher folder)Affected if D.Launcher 2 is present on the system
-
Determine installed D.Launcher 2 versionLocate the main D.Launcher executable, right-click and view Properties > Details to find the Product Version fieldAffected if Version cannot be determined or falls within the vulnerable release range
-
Identify registered custom URL handlersOpen Windows Registry and search HKEY_CLASSES_ROOT for URL scheme entries (commonly 'eid' or similar prefixes) that point to D.Launcher executable paths, or use 'assoc' command in elevated prompt to list file associationsAffected if Custom URL handlers linked to D.Launcher 2 are registered on the system
-
Inspect URL handler command configurationExamine the shell\open\command registry subkey for identified D.Launcher URL handlers to see how URLs are processedAffected if The handler accepts and processes arbitrary URLs without visible validation logic
If D.Launcher 2 is installed and has custom URL handlers registered that accept external URLs, the environment is potentially affected by this SSRF vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply available patches or updates to D.Launcher 2 that implement proper URL handler validation and sanitization; if no patch exists, consider disabling unused custom URL handlers and educating users about not clicking untrusted links.
