CVE-2026-9183 24liveblog CVE debrief
The 24liveblog - live blog tool plugin for WordPress is vulnerable to Exposure of Sensitive Information in versions up to, and including, 2.2. This vulnerability allows authenticated attackers, with contributor-level access and above, to extract third-party 24liveblog account credentials by inspecting the page source in the block editor. The issue arises from the lb24_block_enqueue_scripts() function being hooked to enqueue_block_editor_assets, which falls back to loading administrator-configured site-wide 24liveblog integration secrets for non-administrator users. Affected users should update to a patched version as soon as possible. WordPress site administrators should review their 24liveblog plugin configuration and consider limiting access to the block editor. Additionally, users should be cautious when inspecting page sources for sensitive information.

Authenticated attackers with contributor-level access and above can exploit this issue to extract sensitive 24liveblog account credentials. Site administrators should prioritize updating to a patched version and review their plugin configuration.
Technical summary
The 24liveblog - live blog tool plugin for WordPress is vulnerable to Exposure of Sensitive Information due to the lb24_block_enqueue_scripts() function being hooked to enqueue_block_editor_assets. For non-administrator users, this function falls back to loading administrator-configured site-wide 24liveblog integration secrets (lb24_token, lb24_refresh_token, lb24_uid, lb24_uname) from the options table via get_option() and emits them through wp_localize_script() as the lb24BlockData JavaScript object. This allows authenticated attackers with contributor-level access and above to extract third-party 24liveblog account credentials by inspecting the page source in the block editor.
Defensive priority
Medium priority should be given to updating the 24liveblog - live blog tool plugin to a patched version. Site administrators should review their plugin configuration and consider limiting access to the block editor to mitigate the risk of sensitive information exposure.
