Koa is expressive middleware for Node.js using ES2017 async functions. Prior to versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3, Koa uses an evil regex to parse the `X-Forwarded-Proto` and `X-Forwarded-Host` HTTP headers. This can be exploited to carry out a Denial-of-Service attack. Versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3 fix the issue.

The Koalendar – Events & Appointments Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘height’ parameter in all versions up to, and including, 1.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

A vulnerability was found in Xinhu RockOA 2.6.3 and classified as problematic. Affected by this issue is the function okla of the file /webmain/public/upload/tpl_upload.html. The manipulation of the argument callback leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-271994 is the identifier assigned to this vulnerability.

Rockoa <2.3.3 is vulnerable to SQL Injection. The problem exists in the indexAction method in reimpAction.php.

@koa/cors npm provides Cross-Origin Resource Sharing (CORS) for koa, a web framework for Node.js. Prior to version 5.0.0, the middleware operates in a way that if an allowed origin is not provided, it will return an `Access-Control-Allow-Origin` header with the value of the origin from the request. This behavior completely disables one of the most crucial elements of browsers - the Same Origin Policy (SOP), this could cause a very serious security threat to the users of this middleware. If such behavior is expected, for instance, when middleware is used exclusively for prototypes and not for production applications, it should be heavily emphasized in the documentation along with an indication of the risks associated with such behavior, as many users may not be aware of it. Version 5.0.0 fixes this vulnerability.

A vulnerability was found in Xinhu RockOA 2.3.2. It has been classified as problematic. This affects the function start of the file task.php?m=sys|runt&a=beifen. The manipulation leads to exposure of backup file to an unauthorized control sphere. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-240927.

A vulnerability was found in Xinhu RockOA 1.1/2.3.2/15.X3amdi and classified as problematic. Affected by this issue is some unknown functionality of the file api.php?m=reimplat&a=index of the component Password Handler. The manipulation leads to weak password recovery. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-240926 is the identifier assigned to this vulnerability.

A vulnerability was found in Rockoa 2.3.2. It has been declared as critical. This vulnerability affects unknown code of the file webmainConfig.php of the component Configuration File Handler. The manipulation leads to code injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-224674 is the identifier assigned to this vulnerability.

The manipulation of the argument fileid leads to unrestricted upload. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-223401 was assigned to this vulnerability.

A cross-site request forgery (CSRF) in Rockoa v1.9.8 allows an authenticated attacker to arbitrarily add an administrator account.
