GHSA-FPRF-R6RV-XG99 Vikunja: Saved filter creation with an empty filter string recalculates task positions across all tenants

Summary In Vikunja v2.6.0 the task position recalculation that runs when a saved filter view is created fails open when the requesting user has no accessible projects. Instead of aborting, the search that feeds the recalculation loses its project scope entirely and returns every task in the...

GHSA-J3HG-9RP3-5HW9 Nginx UI: Unauthenticated signed-request body staging can exhaust temporary storage

Summary In Nginx UI versions 2.5.0 through 2.5.x, the node-signature authentication path staged an attacker-controlled request body in a temporary file and synchronized it to disk before validating the body digest and cryptographic signature. An unauthenticated remote client that can reach the AP...

GHSA-9H23-53F4-Q947 Nginx UI: Bundled reverse proxy can bypass IP allowlists and enable shared login lockout

Summary In Nginx UI versions 2.2.0 through 2.5.x, the official bundled reverse-proxy topology did not preserve the external client identity used by Gin. The backend treated the local proxy peer as the client because no trusted proxy was configured, while the proxy supplied the actual address in...

GHSA-X34J-47HF-4XG7 TinaCMS admin preview iframe loads an attacker-controlled origin from the URL fragment

Summary The TinaCMS admin builds its preview from the // hash-router splat without checking that the value stays same-origin. A fragment with a doubled slash ///attacker.example/p becomes the protocol-relative URL //attacker.example/p, so the admin frames an external site. That same unvalidated...

GHSA-8WVG-R2J4-3737 Vikunja: Assignee email addresses disclosed to read-only project members via the task assignees endpoint

Summary TaskAssginee.ReadAll returns assignee user objects without blanking the Email field, disclosing assignee email addresses to any read-only project member. Every sibling path that returns user objects obfuscates the email; this one does not. Details pkg/models/taskassignees.go lines 306-344...

GHSA-3HC7-R24J-RPWC Vikunja: Cross-project task disclosure through subtask expansion

Summary Vikunja lets a task in one project have a subtask that lives in a different project. When listing a project's tasks, an option pulls in those subtasks ?expand%5B%5D=subtasks. The main listing is correctly filtered to the projects the caller can access, but the subtask expansion is not: it...

GHSA-X2RP-9QF7-2FMQ Contao: Protected page content is disclosed to anonymous visitors after contao.search.index_protected is disabled

ModuleSearch decides whether to filter protected pages out of search results based on the current value of contao.search.indexprotected, but the authorisation data lives per row in tlsearch. Turning the setting off removes the filter without removing the rows, so protected pages that were indexed...

GHSA-9FF2-P842-45WQ Contao: Cross-site request forgery in custom backend actions

RequestTokenListener is the only generic REQUESTTOKEN validator in Contao and it only runs on POST. On the GET side the guard is local and declarative, and it only fires when an act parameter is present. Every back end action dispatched through a different parameter therefore has no CSRF protecti...

GHSA-628F-V4F6-P37R Contao: Cross-site scripting in the comments bundle

An unauthenticated front end visitor can post a comment containing a XSS injection. The victim is any back end user who opens the Comments module, and moderation makes exposure certain rather than preventing it. No Content-Security-Policy header is sent on the Contao back end, so nothing mitigate...

GHSA-5974-GFQC-WRCM Contao: Improper access control in the table access voter

Due to a caching defect in the security voter that governs table-level access to Contao's Data Container DCA backend, a low-privileged, non-admin backend user can obtain unauthorized read, create, update, and delete access to database tables outside their assigned module permissions. This include...

GHSA-VFXW-3X8P-2VJR Vikunja: Link-share token can enumerate users through the v2 API

Summary A link-share token, the credential you hand out to let someone view a shared project, can call the v2 user-search endpoints, which it was never meant to reach. The v1 versions of the same endpoints correctly reject link-share tokens; the v2 versions don't. As a result, anyone with a share...

GHSA-39P5-2WRR-XH29 Vikunja: Any user can enumerate every team and its members by attaching arbitrary teams to a throwaway project

Summary When you share a project with a team, the API lets you attach any team on the instance, including teams you have nothing to do with, as long as you're an admin of the project. Listing a project's teams then returns each team's full member roster. So any logged-in user can spin up a...

GHSA-M469-88XX-8RX2 Vikunja: CalDAV and feeds BasicAuth endpoints have no rate limit, bypassing the anti-brute-force floor on account passwords

Summary The /dav, /.well-known, and /feeds groups are registered on the root Echo instance with only BasicAuth and no rate limiter. CalDAV BasicAuth accepts the plain account password, so password guessing over /dav is unbounded and never returns 429, while /api/v1/login is throttled from the ten...

GHSA-9RG3-V78M-26Q8 Vikunja: API token scopes bypassed via task expand parameter (comments, reactions, time entry counts)

Summary API token permission checks only match the HTTP method and route path. The expand query parameter on task read endpoints embeds data from other permission groups task comments, reactions, time entry counts without checking whether the token holds those scopes. A token scoped only to tasks...

GHSA-QFWC-VX6F-3G6G Vikunja: Read-only project members can obtain any link share's access hash via the single-share read endpoint (v1 and v2) and escalate to the share's permission level

Summary A user who has only read permission on a project can call the single link-share read endpoint and receive the share's hash field — the secret credential that the anonymous POST /shares/share/auth endpoint exchanges for a link-share JWT carrying the share's permission read / read-write /...

GHSA-88F6-4RJV-X774 Vikunja: TOTP secret is readable after enrollment, no step-up auth

Summary Once a user has TOTP enabled, the API still hands back the raw shared secret to anyone holding that account's access token. Reading it doesn't ask for the password, even though disabling TOTP does. So a stolen token, an XSS, or a browser left open is enough to copy the second factor into...

GHSA-R6W9-259G-GWRV Vikunja: Plaintext storage of password-reset/email-confirm tokens in database enables account takeover on DB read access

Summary Vikunja stores password-reset, email-confirmation, and account-deletion tokens in the usertokens table in plaintext. If an attacker gains read access to the database through a backup leak, misconfigured storage, or SQL-level exposure, they can immediately use pending tokens to take over...

GHSA-3HJ7-6VMJ-H8V4 pacioli: A submit consent marker licensed cancellation of caller-named pre-existing documents

Impact pacioli-guard's document-layer consent gate requires a human-minted, single-use, document-bound and act-bound marker before a credential carrying API Key Scope.requireconsent may submit or cancel a document. Because ERPNext performs further document writes as a consequence of a governed ac...

GHSA-RJ9J-8772-4H6C Vikunja: Link-share token reads any tenant's kanban buckets and enumerates usernames/IDs instance-wide (BOLA)

Summary The task-collection endpoint GET /api/v1/projects/project/views/view/tasks loads the requested project view straight from the URL path without verifying the caller is authorized for it. For a link-share token, the task query is correctly pinned to the share's own project, but the view is...

GHSA-V3P6-34MC-HJ7V Vikunja: Scoped API token can mint unrestricted OAuth session credentials

Summary A scoped API token can bypass its declared permissions by using the OAuth authorization flow to mint normal session credentials. A token limited to: json "oauth":"authorize" can call /api/v1/oauth/authorize, receive an OAuth authorization code, exchange it at /api/v1/oauth/token, and obta...

GHSA-9Q47-3CM2-2RP8 pyLoad: Rate-Limit Bypass and Audit-Log Spoofing via Trusted Client-Controlled `X-Forwarded-For` Header

Summary pyLoad determines the "client IP" used for its rate-limiting decorator and for its security/audit logging by reading the client-supplied X-Forwarded-For XFF HTTP header and taking the leftmost value. No trusted-proxy configuration exists the Cheroot WSGI server faces clients directly, and...
