CVE-2023-36813: Kanboard Authenticated SQL Injections vulnerability

Kanboard is project management software that focuses on the Kanban methodology. In versions prior to 1.2.31authenticated user is able to perform a SQL Injection, leading to a privilege escalation or loss of confidentiality. It appears that in some insert and update operations, the code improperly uses the PicoDB library to update/insert new information. Version 1.2.31 contains a fix for this issue.

Security readout for executives and security teams

Plain-English summary

CVE-2023-36813 lets a logged-in Kanboard user abuse SQL injection flaws in versions before 1.2.31. The main business risk is unauthorized access to sensitive project data and possible privilege escalation inside the application. Public sources name a fixed release, but do not show active exploitation.

Executive priority

Treat this as a high-priority application update for affected Kanboard systems. The issue is not described as actively exploited, but it can expose confidential project data from a low-privilege account.

Technical view

Kanboard before 1.2.31 improperly used the PicoDB library during some insert and update operations, creating authenticated SQL injection exposure. The CVSS 3.1 score is 7.1 with low attack complexity, low privileges required, no user interaction, high confidentiality impact, and low integrity impact.

Likely exposure

Exposure is limited to organizations running Kanboard versions earlier than 1.2.31, especially where many internal or external users have accounts. Attackers need valid application credentials, so internet exposure matters less than account population and credential hygiene.

Exploitation context

The provided sources do not indicate CISA KEV listing or confirmed active exploitation. The flaw is still serious because exploitation requires only a normal authenticated user and can affect confidentiality and privileges.

Researcher notes

Focus validation on authenticated attack surface and code paths involving PicoDB insert and update operations. The public description is concise and does not enumerate every vulnerable operation, so avoid assuming broader impact beyond Kanboard before 1.2.31.

Mitigation direction

  • Upgrade Kanboard to version 1.2.31 or later.
  • Apply Debian DSA-5454 updates where Kanboard is installed from Debian packages.
  • Check Kanboard and distribution guidance for deployment-specific instructions.
  • Review Kanboard account access until upgrades are complete.

Validation and detection

  • Inventory all Kanboard deployments and record current versions.
  • Flag any instance running a version earlier than 1.2.31.
  • Confirm upgraded systems report version 1.2.31 or later.
  • For Debian deployments, confirm DSA-5454 fixed packages are installed.
  • Review recent authenticated activity for unusual data changes or access.
