The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to incomplete validation in Web IDE. A remote attacker can steal tokens and access private repositories.
2) Input validation error (CVE-ID: CVE-2025-8099)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in GraphQL introspection. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2026-0958)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in JSON validation middleware. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Cross-site scripting (CVE-ID: CVE-2025-14560)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in Code Flow. A remote user can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
5) Stored cross-site scripting (CVE-ID: CVE-2026-0595)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in test case titles. A remote user can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
6) Input validation error (CVE-ID: CVE-2026-1458)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Markdown processor. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2026-1456)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Markdown Preview. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in dashboard. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
9) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-12575)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in Virtual Registry. A remote user can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
10) Input validation error (CVE-ID: CVE-2026-1094)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to improper validation in diff parser. A remote user can hide specially crafted file changes from the WebUI.
11) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-12073)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in Git repository import. A remote user can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
