Title
JeecgBoot Third-Party Login ThirdLoginController.java HttpServletResponse.sendRedirect redirect
Summary
A weakness has been identified in JeecgBoot up to 3.9.2. Impacted is the function HttpServletResponse.sendRedirect of the file jeecg-module-system/jeecg-system-biz/src/main/java/org/jeecg/modules/system/controller/ThirdLoginController.java of the component Third-Party Login. This manipulation of the argument state causes open redirect. The attack can be initiated remotely. A high degree of complexity is needed for the attack. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The project replied: "After evaluation, this vulnerability has low exploitability in real-world scenarios: 1) Exploiting this vulnerability requires attackers to use social engineering techniques to induce victims to actively click on an OAuth login link constructed by the attacker; it cannot be triggered passively. 2) Third-party login (DingTalk/WeChat, etc.) is an optional feature and may not be enabled in most projects."

CVE-2026-12049 (GCVE-0-2026-12049)

Title
pgAdmin 4: Open redirect in multi-factor authentication flow via unvalidated 'next' parameter
Summary
Open redirect in pgAdmin 4's multi-factor authentication flow. The MFA validate and register endpoints honoured the user-supplied 'next' query/form parameter without confirming the target pointed back inside pgAdmin, so an authenticated victim who clicked /mfa/validate?next=<external> -- a link typically delivered by phishing -- would be sent to an attacker-controlled host directly out of the trusted auth flow. The defect is a trusted-domain redirect, not a privilege bypass: the attacker gains no read/write access to pgAdmin or the victim's database, but the redirect launders the attacker's destination through pgAdmin's URL, which raises the success rate of credential-phishing follow-on against the victim. Fix introduces a same-origin _is_safe_redirect_url helper and gates every MFA redirect that consumes user-supplied 'next' values through it. The helper allows only relative paths and absolute URLs whose scheme is http(s) and whose host matches the current request host; it rejects external hosts in absolute and protocol-relative form, non-http schemes (javascript:, data:, mailto:), userinfo tricks (http://localhost@attacker/), and backslash variants that some browsers normalize to forward slashes. Unsafe targets fall back to the internal browser index. A dedicated regression test exercises each accept/reject category and the original reporter PoC. This issue affects pgAdmin 4: from 6.0 before 9.16.

The endpoint requires login_required so the victim must already be authenticated to pgAdmin -- but the *attacker* needs no pgAdmin privileges at all to construct and deliver the link (PR:N). UI:R captures the click. Scope is unchanged: the defect does not grant the attacker access to pgAdmin\u0027s authority or the victim\u0027s database session; it only launders the attacker\u0027s destination through pgAdmin\u0027s URL, which raises credential-phishing success rates. C:N and A:N follow from the same reasoning; I:L acknowledges the integrity impact of an authenticated-flow redirect that lends pgAdmin\u0027s trust to an attacker domain.\n\nReviewer note (Dave Page, 2026-06-11): defensible at 4.3 for a token-free open redirect. Heads-up that NVD house style for open redirects often lands at S:C/C:L/I:L -\u003e 6.1, so expect a possible upward rescore by the NVD analyst."

Title
URL Shortify <= 1.12.1 - Unauthenticated Open Redirect via 'redirect_to' Parameter
Summary
The URL Shortify plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 1.12.1 due to insufficient validation on the 'redirect_to' parameter in the promotional dismissal handler. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites via a crafted link.

Title
Frontend Post Submission Manager Lite <= 1.2.7 - Unauthenticated Open Redirect via 'requested_page' Parameter
Summary
The Frontend Post Submission Manager Lite plugin for WordPress is vulnerable to Open Redirection in all versions up to, and including, 1.2.7 due to insufficient validation on the 'requested_page' POST parameter in the verify_username_password function. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action such as clicking on a link.

Title
Lack of input validation in Mailerup input parameter leads to Open Redirect
Summary
Open redirect vulnerability (CWE-601) in the _safe_redirect function of the click-tracking endpoint (/c/<token>/) in Mailerup <1.0.0 on all platforms allows remote unauthenticated attackers to redirect victims to arbitrary external sites and conduct phishing attacks via a crafted u query parameter, because the URL scheme is validated (blocking javascript: and data:) but the destination host is not restricted to an allowlist, and a signing.BadSignature exception is silently caught so a valid signed token is not required.

Mitigation ID: MIT-5

Phase: Implementation

Strategy: Input Validation

Description:

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • Use a list of approved URLs or domains to be used for redirection.
Mitigation

Phase: Architecture and Design

Description:

  • Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Mitigation ID: MIT-21.2

Phase: Architecture and Design

Strategy: Enforcement by Conversion

Description:

  • When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
  • For example, ID 1 could map to "/login.asp" and ID 2 could map to "http://www.example.com/". Features such as the ESAPI AccessReferenceMap [REF-45] provide this capability.
Mitigation

Phase: Architecture and Design

Description:

  • Ensure that no externally-supplied requests are honored by requiring that all redirect requests include a unique nonce generated by the application [REF-483]. Be sure that the nonce is not predictable (CWE-330).
Mitigation ID: MIT-6

Phases: Architecture and Design, Implementation

Strategy: Attack Surface Reduction

Description:

  • Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
  • Many open redirect problems occur because the programmer assumed that certain inputs could not be modified, such as cookies and hidden form fields.
Mitigation ID: MIT-29

Phase: Operation

Strategy: Firewall

Description:

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
CAPEC-178: Cross-Site Flashing

An attacker is able to trick the victim into executing a Flash document that passes commands or calls to a Flash player browser plugin, allowing the attacker to exploit native Flash functionality in the client browser. This attack pattern occurs where an attacker can provide a crafted link to a Flash document (SWF file) which, when followed, will cause additional malicious instructions to be executed. The attacker does not need to serve or control the Flash document. The attack takes advantage of the fact that Flash files can reference external URLs. If variables that serve as URLs that the Flash application references can be controlled through parameters, then by creating a link that includes values for those parameters, an attacker can cause arbitrary content to be referenced and possibly executed by the targeted Flash application.
