+  "details": "### Summary\nThe 'sharing FAQ' functionality allows any unauthenticated actor to misuse the phpMyFAQ application to send arbitrary emails to a large range of targets.\n\n### Details\nThe phpMyFAQ application has a functionality where anyone can share a FAQ item to others. The front-end of this functionality allows any phpMyFAQ articles to be shared with 5 email addresses. The application will then send these 5 emails. However, there are no controls over what link and content are shared. Furthermore, any unauthenticated actor can perform this action. There is a CAPTCHA in place, however the amount of people you email with a single request is not limited to 5 by the backend. An attacker can thus solve a single CAPTCHA and send thousands of emails at once. \n\n### PoC\nWe send the following form and capture the request.\n![image](https://user-images.githubusercontent.com/44903767/296291204-4a472536-9838-4f9e-bd95-df3d886af43f.png)\n\nWe now change the body to contain 50 email addresses instead of just 1, and send the request. The attacker can also change the body of the email to any phishing message.\n![image](https://user-images.githubusercontent.com/44903767/296291441-bba85a6c-45be-4f07-9385-e6da27713e35.png)\n\nBelow are the logs of the email server, proving that all these emails were sent.\n![image](https://user-images.githubusercontent.com/44903767/296291673-d324be20-74b9-4e16-b25d-aa9b1dd75d5a.png)\n\nAn attacker can also change the link that is sent in these emails. Making phishing even more possible.\n![image](https://user-images.githubusercontent.com/44903767/296291897-8c0a40e7-cd4b-4021-8f4d-4362e10ad36b.png)\n\n### Impact\nAn attacker can utilize the target application's email server to send phishing messages. This can get the server on a blacklist, causing all emails to end up in spam. It can also lead to reputational damages.\n",

+  "details": "## Summary\n\nNokogiri v1.16.2 upgrades the version of its dependency libxml2 to [v2.12.5](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.12.5).\n\nlibxml2 v2.12.5 addresses the following vulnerability:\n\n- CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062\n  - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604\n  - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970\n\nPlease note that this advisory only applies to the CRuby implementation of Nokogiri `< 1.16.2`, and only if the _packaged_ libraries are being used. If you've overridden defaults at installation time to use _system_ libraries instead of packaged libraries, you should instead pay attention to your distro's `libxml2` release announcements.\n\n## Mitigation\n\nUpgrade to Nokogiri `>= 1.16.2`.\n\nUsers who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against external libraries libxml2 `>= 2.12.5` which will also address these same issues.\n\n## Impact\n\nFrom the CVE description, this issue applies to the `xmlTextReader` module (which underlies `Nokogiri::XML::Reader`):\n\n> When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.\n\n## Timeline\n\n- 2024-02-04 10:35 EST - this GHSA is drafted without complete details about when the upstream issue was introduced; a request is made of libxml2 maintainers for more detailed information\n- 2024-02-04 10:48 EST - updated GHSA to reflect libxml2 maintainers' confirmation of affected versions\n- 2024-02-04 11:54 EST - v1.16.2 published, this GHSA made public\n- 2024-02-05 10:18 EST - updated with MITRE link to the CVE information, and updated \"Impact\" section",
