🚨 CVE-2026-83801
Nautobot is a Network Source of Truth and Network Automation Platform. Prior to 2.4.37 and 3.1.8, a user with extras.add_relationship or extras.change_relationship permission can store HTML or JavaScript in a Relationship description, and a user with dcim.add_modulefamily or dcim.change_modulefamily permission can store it in a Module Family name. Nautobot assigns these values to form field help_text rendered by render_field.html through Django's |safe filter without adequate neutralization. The stored content executes in the authenticated browser session of any user, including an administrator or superuser, who opens an affected create or edit form. This can enable actions as the victim, session or token theft, and further privilege escalation. This issue is fixed in versions 2.4.37 and 3.1.8.

🚨 CVE-2026-83805
Nautobot is a Network Source of Truth and Network Automation Platform. From 3.0.0 until 3.1.8, the generic ApprovalWorkflowStageResponse create endpoint does not enforce approver-group membership, change permission on the object under review, or the one-response-per-user restriction applied by the intended approve and deny actions. A user with only extras.add_approvalworkflowstageresponse can submit approved responses directly, while writable user and state fields permit responses to be attributed to arbitrary users. These forged responses can satisfy min_approvers, approve the workflow, and activate its gated ScheduledJob without a legitimate approver. This issue is fixed in version 3.1.8.

wlc is a Weblate command-line client using Weblate's REST API. Prior to 2.0.1, automatically discovered configuration from .weblate, .weblate.ini, or weblate.ini can select the API URL while an unscoped API token is supplied through WLC_KEY or --key without a matching WLC_URL or --url. When wlc runs in an untrusted repository, pull request checkout, or directory with untrusted ancestor configuration, it can send the token to an attacker-controlled project-configured URL. URL-scoped keys in [keys] are not affected. This issue is fixed in version 2.0.1.

Unleash is an open-source feature management platform. Prior to 8.0.3, the change-request approval email template at src/mailtemplates/requested-cr-approval/requested-cr-approval.html.mustache renders the user-controlled changeRequestTitle, requesterName, and requesterEmail values without HTML escaping, and sendRequestedCRApprovalEmail passes those values to Mustache rendering. A project member who can create a change request when approval emails are enabled can inject HTML into an approver's notification, allowing forged links, tracking content, or visually altered email content. This issue is fixed in version 8.0.3.

🚨 CVE-2026-77425
Unleash is an open-source feature management platform. Prior to 8.0.3, POST /api/admin/projects/:projectId/features/:featureName/environments/:environment/strategies/set-sort-order passes attacker-controlled strategy IDs to unprotectedUpdateStrategiesSortOrder and updateSortOrder without verifying that the IDs belong to the project, feature, and environment authorized by the URL. In a multi-project Pro or Enterprise deployment, an authenticated user with UPDATE_FEATURE_STRATEGY in one project who knows another project's strategy IDs can reorder those strategies, changing feature evaluation precedence while the operation is attributed to the attacker's URL context rather than the affected project. The single-project OSS edition lacks the cross-project dimension, although the missing context binding still permits unauthorized reordering across features or environments in the default project. The endpoint changes only sort_order and does not modify strategy parameters, constraints, or segments. This issue is fixed in version 8.0.3.
