CVE-2026-81819

Affected versions of Flowintel expose the /myassignment/user API endpoint to any authenticated API user. The endpoint accepts a userid parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication. As a result, a...

CVE-2026-81820

Affected versions of Flowintel construct timeline HTML using attacker-controllable MISP object fields such as: object UUID; object name; attribute value; attribute type; comment; first/last seen values; IDS flag. Those values were concatenated directly into HTML strings before rendering. The...

CVE-2026-81817

Affected versions of Flowintel contain an insecure direct object reference / broken object-level authorization issue across numerous task endpoints. The routes generally received both a case identifier and a task identifier, but previously they did not enforce that the task actually belonged to t...

CVE-2026-81818

Affected versions of Flowintel contain an authorization flaw in the administrative user-edit API. The existing authorization check correctly prevented an organization administrator from editing users in another organization, but it did not prevent them from editing a full administrator within the...

CVE-2026-81826

Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed. This means that if an attacker already possesses a valid session—for example, from prior access or a stolen session token—the victim changing their password does not terminate that...

CVE-2026-81827

Affected versions of Flowintel incorrectly attempted to validate login email addresses by calling Emailemail. That does not perform WTForms field validation; it merely constructs a validator object. Consequently, malformed attacker-controlled email input could continue through the login process a...

CVE-2026-81827 Flowintel Login Email Validation Bypass Allows Log Injection via Crafted Email Input

Affected versions of Flowintel incorrectly attempted to validate login email addresses by calling Emailemail. That does not perform WTForms field validation; it merely constructs a validator object. Consequently, malformed attacker-controlled email input could continue through the login process a...

CVE-2026-81827

Flowintel versions >=3.3.0 contained a validation flaw in the login flow: the code called Email(email) (which only constructs a WTForms validator object) instead of Email()(form, form.email), so malformed attacker-supplied email values bypassed validation. Because CR/LF characters in the email...

CVE-2026-81826 Flowintel Fails to Invalidate Active Sessions After Password Change

Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed. This means that if an attacker already possesses a valid session—for example, from prior access or a stolen session token—the victim changing their password does not terminate that...

CVE-2026-81826

Flowintel (versions >=3.3.0 ) fails to revoke existing authenticated sessions when a user's password is changed. An attacker who already holds a valid session token retains access until that session expires naturally, even after the victim changes their password. The fix detects password chang...

CVE-2026-81820

Flowintel versions greater than 3.3.0 are vulnerable to HTML injection in the MISP case history timeline. Attacker-controllable MISP object fields (object UUID, name, attribute value, attribute type, comment, first/last seen, and IDS flag) were concatenated directly into HTML strings before rende...

CVE-2026-81820 Flowintel HTML Injection in MISP Case History Timeline via Crafted Object Attributes

Affected versions of Flowintel construct timeline HTML using attacker-controllable MISP object fields such as: object UUID; object name; attribute value; attribute type; comment; first/last seen values; IDS flag. Those values were concatenated directly into HTML strings before rendering. The...

CVE-2026-81819 Flowintel Missing Authorization Allows Regular API Users to View Other Users’ Task Assignments

Affected versions of Flowintel expose the /myassignment/user API endpoint to any authenticated API user. The endpoint accepts a userid parameter identifying the user whose assignments should be returned, but previously had no role restriction beyond general API authentication. As a result, a...
