Snipe It CVE-2026-55843

Q: Which versions of Snipe It are affected by CVE-2026-55843?

Snipe-IT versions before 8.6.0 contain a permission-handling vulnerability allowing administrators to silently strip administrative access from other accounts, including other administrators.. A patch is available.

Q: How to fix or mitigate CVE-2026-55843?

Within 24 hours: Review Snipe-IT audit logs for recent unauthorized permission revocations; export a list of all users with Admin role or users.edit permission; implement available access controls (IP whitelisting, MFA) for user management functions if supported. Within 7 days: Back up production Snipe-IT database; test and validate Snipe-IT 8.6.0 or later upgrade in staging environment; create upgrade runbook and rollback plan. Within 30 days: Execute production upgrade to Snipe-IT 8.6.0 or later; verify all user permissions post-upgrade; audit permission changes made prior to upgrade for suspicious activity.

AnalysisAIv1 – Jul 10, 2026

Improper permission handling in Snipe-IT before 8.6.0 lets a privileged user strip another user's administrative or granular permissions when editing their account. Because UsersController::update() treats a missing permissions field as a sparse payload rather than a no-op, an administrator editing another administrator — or any user holding users.edit editing a regular account — can silently wipe the target's privileges. No public exploit identified at time of analysis; this is an authenticated integrity/availability issue rather than a remote takeover.

DescriptionCVE.org

Snipe-IT is an IT asset/license management system. Prior to 8.6.0, UsersController::update() passes a missing permission request field through NormalizePermissionsPayloadAction and PreserveUnauthorizedPrivilegedPermissionsAction in a way that can overwrite a target user’s permissions with a sparse result, allowing an administrator updating another administrator, or a user with users.edit updating a regular account, to remove the target’s administrative or granular permissions. This issue is fixed in version 8.6.0.

Executive ViewAI

Why It Matters

Snipe-IT versions before 8.6.0 contain a permission-handling vulnerability allowing administrators to silently strip administrative access from other accounts, including other administrators. This enables privilege-stripping attacks that could disable critical accounts, prevent emergency security operations, or disrupt asset management functions. Organizations should prioritize immediate upgrade to version 8.6.0 or later.

Recommended Action

Within 24 hours: Review Snipe-IT audit logs for recent unauthorized permission revocations; export a list of all users with Admin role or users.edit permission; implement available access controls (IP whitelisting, MFA) for user management functions if supported. Within 7 days: Back up production Snipe-IT database; test and validate Snipe-IT 8.6.0 or later upgrade in staging environment; create upgrade runbook and rollback plan. Within 30 days: Execute production upgrade to Snipe-IT 8.6.0 or later; verify all user permissions post-upgrade; audit permission changes made prior to upgrade for suspicious activity.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
