Halo Surface Signal score for CVE-2026-41462

ProjeQtor is a web-based project management application that requires users to access a login page. These platforms are commonly deployed as internet-facing web applications to facilitate access for remote or distributed teams. As the vulnerability resides in the login endpoint of this web-based interface, it is commonly reachable from the public internet in typical deployments.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability in ProjeQtor allows unauthenticated individuals to inject malicious SQL code through the username field during login. This could let them create admin accounts, steal data, or even run system commands if database permissions are high.

  • Attackers need no credentials.
  • It affects a web-based project management tool.
  • High impact on data confidentiality and integrity.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can exploit this SQL injection vulnerability in ProjeQtor by submitting crafted input to the username field on the login page. This allows them to bypass authentication and execute arbitrary SQL commands. If the database has sufficient privileges, the attacker can then potentially create new administrative accounts, exfiltrate sensitive data, or even execute commands on the underlying operating system.

  • Network access required.
  • Target: Login endpoint.
  • No prior authentication.

Live Threat

Current exploitation, exposure, and threat context

This SQL injection vulnerability in ProjeQtor's login functionality is a prime target for attackers due to its unauthenticated nature and critical impact. The ability to bypass authentication, escalate privileges, and potentially execute OS commands makes it extremely valuable for initial access or data exfiltration. The direct concatenation of user input into SQL queries without sanitization is a well-understood and easily weaponized flaw.

  • Exploitable via login endpoint.
  • Direct impact on data and privileges.
  • No authentication required.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize blocking traffic to the ProjeQtor login endpoint from unauthenticated sources to prevent SQL injection. Investigate any unusual database activity or unexpected account creations. If exploitation is detected, immediately isolate affected instances.

  • Block unauthenticated login requests.
  • Monitor for suspicious database queries.
  • Isolate compromised instances immediately.

Frequently asked questions

What is ProjeQtor and what is it used for?

ProjeQtor is a web-based project management application. People use it to manage projects, track tasks, and collaborate on project-related activities.

What type of vulnerability does CVE-2026-41462 represent?

CVE-2026-41462 is a SQL injection vulnerability. This weakness occurs when user input, like a username, is used directly in a database query without proper checking, allowing attackers to insert malicious SQL commands.

How can an attacker exploit this ProjeQtor vulnerability?

An attacker can exploit this flaw by entering specially crafted SQL code into the username field when attempting to log in. They do not need any prior authentication or special privileges to trigger this vulnerability.

Who should be concerned about CVE-2026-41462?

Organizations running ProjeQtor should be concerned. Because ProjeQtor is a web-based application, it is often internet-facing, meaning attackers from outside the network could potentially exploit this vulnerability.

What is the first step for responding to this ProjeQtor vulnerability?

The immediate first step is to investigate any unusual activity within your ProjeQtor system or associated databases. Additionally, review access logs for the login endpoint to identify any suspicious login attempts.
