Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

    Weakness class (CWE)

    CWE-352 · Cross-Site Request Forgery (CSRF)

    CVSS vector

    AV:N/AC:M/Au:N/C:P/I:P/A:P

    nvd-primary

    Root cause

    State-changing requests rely on the session cookie the browser sends automatically; nothing verifies that the request came from the user’s own page.
