Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.1 and 6.5.4, the OAuth callback endpoints for Microsoft, Google, and Facebook external credentials do not validate a CSRF state parameter. This vulnerability is fixed in 7.0.1 and 6.5.4.

CVE-2026-71378——
——0ResourceIsolationRequestCycleListener protects a Wicket application against cross-site request forgery by rejecting requests that a resource isolation policy judges to come from another origin. Its default policy, FetchMetadataResourceIsolationPolicy, was derived from a reference implementation written to guard static resources, and it inherited two allowances that are unsafe when the thing being guarded is an action on a page:
* Every "simple top-level navigation" was allowed. Any GET request carrying Sec-Fetch-Mode: navigate whose Sec-Fetch-Dest was neither object nor embed was allowed, whatever Sec-Fetch-Site said — including cross-site. Wicket invokes component listeners (Link.onClick(), form submits, behaviour callbacks) through ordinary GET navigations, so a page under an attacker's control could navigate the victim's browser to a listener URL and have that listener run inside the victim's authenticated session. Browsers send SameSite=Lax cookies — the effective default when no SameSite attribute is set — on cross-site top-level GET navigations, so the victim's session cookie accompanied the request.
* Sec-Fetch-Site: same-site was allowed unconditionally. That value means the same registrable domain and scheme but a different origin — another subdomain or another port. Any sibling origin could therefore invoke any listener by any method, POST form submits included, and cookies are always sent on same-site requests regardless of SameSite. A hostile sibling origin obtained through a subdomain takeover, through delegated user content, or through an XSS elsewhere on the site could act as the authenticated user.
Users are recommended to upgrade to version 9.24.0 or 10.11.0, which fix the issue.
Affected versions
* Apache Wicket 9.1.0 through 9.23.0
* Apache Wicket 10.0.0 through 10.10.0
Not affected
Any release older than 9.1.0:
* Apache Wicket 8.x (8.0.0 through 8.17.0). The resource isolation classes do not exist in the 8.x line, which offers only the Origin/Referer-based CsrfPreventionRequestCycleListener. No 8.x release requires a fix.
* Apache Wicket 9.0.0. ResourceIsolationRequestCycleListener and FetchMetadataResourceIsolationPolicy were introduced by WICKET-6786 and first shipped in 9.1.0 (released 2020-10-07).3hCVE-2026-826476.1 MED1.1%
——0WWBN AVideo contains a cross-site request forgery vulnerability in sendEmail.json.php that allows authenticated administrators to send mail from the site's contact address by bypassing origin checks and captcha validation. Attackers can craft a malicious web page that, when visited by an authenticated admin, sends emails with attacker-controlled subject and body to arbitrary recipients, passing SPF/DKIM/DMARC validation for phishing and brand impersonation attacks.5hCVE-2026-825444.3 MED6.5%
——2A flaw has been found in wger-project wger up to 2.6.0-alpha2. This issue affects the function reset_user_password of the file wger/gym/views/gym.py of the component Password Reset. Executing a manipulation can lead to cross-site request forgery. It is possible to launch the attack remotely. This patch is called 3c6ce4b7f3eeafeb35318c6c4e82b1a3fd28b314. It is advisable to implement a patch to correct this issue.1dCVE-2026-824684.7 MED2.2%
——1Rodauth before 2.47.0 contains a cross-site request forgery protection bypass vulnerability in the JSON request content type validation. Attackers can craft cross-origin form posts with content types containing application/json substrings to bypass CSRF token validation and force victims to authenticate to attacker-controlled accounts.2dCVE-2026-175225.4 MED0.7%
——0The Newsletters WordPress plugin before 4.17 does not perform any nonce or capability check when saving one of its settings screens, and writes every submitted parameter into its own options, allowing attackers to make a logged in administrator overwrite arbitrary Newsletters WordPress plugin before 4.17 settings, including the credential protecting its API, via a Cross-Site Request Forgery attack.2dCVE-2026-81733—6.7%
——2WWBN AVideo through 30.0 (and master up to commit 4cb576e) contains a cross-site request forgery vulnerability in plugin/Live/myLiveControls.save.json.php. The endpoint only checks that a user is logged in and processes customUrl, customMessage, and autoRedirect parameters from $_REQUEST via a GET request without enforcing a CSRF token or origin check. An attacker who lures a logged-in streamer to a malicious page can silently change the live-channel viewer-redirect settings (persisted in users.externalOptions), causing viewers to be redirected to a phishing site or shown a spoofed message.2d
