GHSA-7VFX-4246-JCFH
Vulnerability from github – Published: 2026-06-26 22:20 – Updated: 2026-06-26 22:20Summary
Four authorization bypass vulnerabilities in Symfony LiveComponent actions allow any authenticated user within a company to access, modify, or delete other users' API tokens and notification transport settings. The root cause is that LiveComponent actions accept entity IDs without verifying ownership, while the listing methods correctly filter by user.
Findings
1. Cross-User API Token Revocation (MEDIUM)
File: src/UserBundle/Twig/Components/ApiTokens.php, lines 50-55
The revoke() LiveAction accepts any ApiToken via #[LiveArg] without checking ownership. The apiTokens() method correctly filters by user (getApiTokensForUser($this->security->getUser())).
#[LiveAction]
public function revoke(#[LiveArg] ApiToken $token): void
{
$this->apiTokenRepository->revoke($token); // No ownership check
}
2. Cross-User API Token History Disclosure (MEDIUM)
File: src/UserBundle/Twig/Components/ApiTokenHistory.php, lines 30-55
The writable $token LiveProp performs $this->apiTokenRepository->find($this->token) without user verification. Exposes IP addresses, request methods, paths, and user agents from other users' API token usage.
3. Cross-User Notification Transport Settings Disclosure (HIGH)
File: src/NotificationBundle/Twig/Components/NotificationIntegrations.php, lines 48-55
The integration() method performs $this->repository->find($this->setting) using a writable LiveProp without user check. The enabledIntegrations() method correctly filters: $this->repository->findBy(['user' => $this->getUser()]).
The TransportSetting entity stores notification credentials in a JSON settings column, potentially exposing API keys for Slack, Discord, Telegram, or SMS services.
4. Cross-User Notification Transport Setting Takeover (HIGH)
File: src/NotificationBundle/Twig/Components/NotificationTransportConfiguration.php, lines 39-40, 84-101
The writable $setting LiveProp accepts any TransportSetting entity. The save() action overwrites the user field with the current user via $setting->setUser($user), effectively stealing the transport configuration and its stored credentials.
Root Cause
The application relies on Doctrine's CompanyFilter for tenant isolation but has no user-level access controls within a company. LiveComponent actions that resolve entities from client-provided IDs don't verify ownership.
Suggested Fix
Add user ownership verification in each LiveAction/LiveProp before performing operations:
if ($token->getUser() !== $this->security->getUser()) {
throw $this->createAccessDeniedException();
}

Vulnerability from github – Published: 2026-10-07 20:28 – Updated: 2026-10-07 20:28Impact
An authenticated user could overwrite an existing S3 object belonging to another upload collection, bypassing that collection’s access controls and prior file validation.
You are affected if ALL of these are true:
- Client uploads are enabled for multiple collections that share an S3 bucket.
- useCompositePrefixes is not configured or is set to false.
Patches
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Workarounds
Disable client uploads until you can upgrade.

GHSA-7VPF-4C24-4XFV
Vulnerability from github – Published: 2026-09-11 21:31 – Updated: 2026-09-18 15:31Concrete CMS before 9.5.3 evaluated the authorization check for an Express entry submission against the entity of the posted form rather than the entity identified by the dashboard route. As a result, a user permitted to add entries to one Express object could create entries in a different Express object outside their authorization scope, potentially polluting protected datasets, triggering workflows, or injecting content into administrative processes. The dashboard submit route resolved the mutated entity from the attacker-controlled route ID while the permission check validated the independently posted form's entity, and the submission proceeded because the two entities were never compared. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.1 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Yonatan Drori from Tenzai for reporting.

Mitigation
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
No CAPEC attack patterns related to this CWE.
