    Advanced Custom Fields: Extended 0.9.2.4 - 0.9.2.7 - Unauthenticated Arbitrary Shortcode Execution via Form Success Message
    Summary
    The Advanced Custom Fields: Extended and Advanced Custom Fields: Extended PRO WordPress plugins from 0.9.2.4 to 0.9.2.7 do not consistently disable shortcode processing in the confirmation message of their front-end forms, allowing unauthenticated visitors to have arbitrary shortcodes executed server-side when they submit a form whose stored configuration does not carry the relevant setting.

    Vulnerability from nvd – Published: 2026-10-23 06:00 – Updated: 2026-10-23 10:46

    Title
    Advanced Custom Fields: Extended 0.9.2.7 - Unauthenticated Administrator Account Takeover via Front-End User Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not resolve the target of the update-user action in its front-end Forms module consistently between the stage that authorises the request and the stage that carries it out, which allows unauthenticated visitors to bypass the guard protecting administrator accounts, take over the site administrator's account and be issued a valid session for it. Exploitation requires the site to publish two separate front-end form configurations whose targets are mapped to visitor-submitted values.

    CVE-2026-94267 (GCVE-0-2026-94267)

    Vulnerability from nvd – Published: 2026-10-23 06:00 – Updated: 2026-10-23 10:46
    VLAI
    Title
    Advanced Custom Fields: Extended < 0.9.2.8 - Unauthenticated RCE via Front-End Post Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not perform any capability check when updating a post through one of its front-end form actions, allowing unauthenticated visitors to overwrite arbitrary posts, including the ones in which the site stores its own field definitions, which in turn leads to arbitrary code execution on the server. Exploitation requires the site to publish a form whose post-update action maps both its target and its content to visitor-submitted values.

    Title
    Advanced Custom Fields: Extended 0.8.9.4 - 0.9.2.7 - Contributor+ XSS via Form Shortcode Attributes
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not validate or escape some of its form shortcode attributes, which can be pointed at values taken from the visitor's own request and are then output without escaping, allowing users with a role as low as contributor to have arbitrary script run in the browser of anyone led to open a crafted link or page, including a logged-in administrator. This is an incomplete fix for CVE-2023-5292, whose deny-list covers only the three HTML wrapper attributes.

    Title
    Advanced Custom Fields: Extended 0.9.2.7 - Unauthenticated Non-Administrator Account Takeover via Front-End User Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not verify that the requester is authorised to edit the targeted user account in the update-user action of its front-end Forms module, performing that check only when the target account holds an administrator role, which allows unauthenticated visitors to overwrite any non-administrator account's credentials and obtain a session for that account. Exploitation requires the site to publish a form whose user-update action maps its target to a visitor-submitted value rather than to the default current user.

    Advanced Custom Fields: Extended 0.9.2.4 - 0.9.2.7 - Unauthenticated Arbitrary Shortcode Execution via Form Success Message
    Summary
    The Advanced Custom Fields: Extended and Advanced Custom Fields: Extended PRO WordPress plugins from 0.9.2.4 to 0.9.2.7 do not consistently disable shortcode processing in the confirmation message of their front-end forms, allowing unauthenticated visitors to have arbitrary shortcodes executed server-side when they submit a form whose stored configuration does not carry the relevant setting.

    Title
    Advanced Custom Fields: Extended 0.9.2.7 - Unauthenticated Administrator Account Takeover via Front-End User Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not resolve the target of the update-user action in its front-end Forms module consistently between the stage that authorises the request and the stage that carries it out, which allows unauthenticated visitors to bypass the guard protecting administrator accounts, take over the site administrator's account and be issued a valid session for it. Exploitation requires the site to publish two separate front-end form configurations whose targets are mapped to visitor-submitted values.

    CVE-2026-94267 (GCVE-0-2026-94267)

    Vulnerability from cvelistv5 – Published: 2026-10-23 06:00 – Updated: 2026-10-23 10:46

    Title
    Advanced Custom Fields: Extended < 0.9.2.8 - Unauthenticated RCE via Front-End Post Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not perform any capability check when updating a post through one of its front-end form actions, allowing unauthenticated visitors to overwrite arbitrary posts, including the ones in which the site stores its own field definitions, which in turn leads to arbitrary code execution on the server. Exploitation requires the site to publish a form whose post-update action maps both its target and its content to visitor-submitted values.

    Title
    Advanced Custom Fields: Extended 0.8.9.4 - 0.9.2.7 - Contributor+ XSS via Form Shortcode Attributes
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not validate or escape some of its form shortcode attributes, which can be pointed at values taken from the visitor's own request and are then output without escaping, allowing users with a role as low as contributor to have arbitrary script run in the browser of anyone led to open a crafted link or page, including a logged-in administrator. This is an incomplete fix for CVE-2023-5292, whose deny-list covers only the three HTML wrapper attributes.

    Title
    Advanced Custom Fields: Extended 0.9.2.7 - Unauthenticated Non-Administrator Account Takeover via Front-End User Update Action
    Summary
    The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not verify that the requester is authorised to edit the targeted user account in the update-user action of its front-end Forms module, performing that check only when the target account holds an administrator role, which allows unauthenticated visitors to overwrite any non-administrator account's credentials and obtain a session for that account. Exploitation requires the site to publish a form whose user-update action maps its target to a visitor-submitted value rather than to the default current user.
