Dbit N300 T1 Pro Firmware: Cross-Site Request Forgery
CVE-2026-36956 is a high-severity cross-site request forgery vulnerability in Dbit N300 T1 Pro Firmware from Dbitnet, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Dbit N300 T1 Pro Firmware versions: 1.0.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.16% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Dbit N300 T1 Pro Firmware you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A Cross-Site Request Forgery (CSRF) vulnerability exists in the web management interface of the Dbit N300 T1 Pro wireless router V1.0.0. The router fails to implement proper CSRF protection mechanisms such as anti-CSRF tokens or strict Origin/Referer validation for administrative API endpoints. An attacker can craft a malicious webpage that sends forged HTTP requests to configuration endpoints such as /api/setWlan. If an authenticated administrator visits the malicious webpage, the victim's browser automatically includes the valid session cookie in the request, allowing the router to process the request as a legitimate administrative action.

The underlying weakness: Cross-Site Request Forgery
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
How developers prevent this class of flaw
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
- Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
- Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
