| CVE-2021-33609 | 1 Vaadin | 1 Vaadin | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| Missing check in DataCommunicator class in com.vaadin:vaadin-server versions 8.0.0 through 8.14.0 (Vaadin 8.0.0 through 8.14.0) allows authenticated network attacker to cause heap exhaustion by requesting too many rows of data. | |||||
| CVE-2021-33580 | 1 Apache | 1 Roller | 2024-11-21 | 4.3 MEDIUM | 7.5 HIGH |
| User controlled `request.getHeader("Referer")`, `request.getRequestURL()` and `request.getQueryString()` are used to build and run a regex expression. The attacker doesn't have to use a browser and may send a specially crafted Referer header programmatically. Since the attacker controls the string and the regex pattern he may cause a ReDoS by regex catastrophic backtracking on the server side. This problem has been fixed in Roller 6.0.2. | |||||
| CVE-2021-33503 | 3 Fedoraproject, Oracle, Python | 5 Fedora, Enterprise Manager Ops Center, Instantis Enterprisetrack and 2 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in urllib3 before 1.26.5.

| CVE-2021-32839 | 1 Sqlparse Project | 1 Sqlparse | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| sqlparse is a non-validating SQL parser module for Python. In sqlparse versions 0.4.0 and 0.4.1 there is a regular Expression Denial of Service in sqlparse vulnerability. The regular expression may cause exponential backtracking on strings containing many repetitions of '\r\n' in SQL comments. Only the formatting feature that removes comments from SQL statements is affected by this regular expression. As a workaround don't use the sqlformat.format function with keyword strip_comments=True or the --strip-comments command line flag when using the sqlformat command line tool. The issues has been fixed in sqlparse 0.4.2. | |||||

| CVE-2021-32823 | 2 Bindata Project, Gitlab | 2 Bindata, Gitlab | 2024-11-21 | 4.3 MEDIUM | 3.7 LOW |
| In the bindata RubyGem before version 2.4.10 there is a potential denial-of-service vulnerability. In affected versions it is very slow for certain classes in BinData to be created. For example BinData::Bit100000, BinData::Bit100001, BinData::Bit100002, BinData::Bit<N>. In combination with <user_input>.constantize there is a potential for a CPU-based DoS. In version 2.4.10 bindata improved the creation time of Bits and Integers. | |||||
| CVE-2021-32821 | 1 Mootools | 1 Mootools | 2024-11-21 | N/A | 6.2 MEDIUM |
| MooTools is a collection of JavaScript utilities for JavaScript developers. All known versions include a CSS selector parser that is vulnerable to Regular Expression Denial of Service (ReDoS). An attack requires that an attacker can inject a string into a CSS selector at runtime, which is quite common with e.g. jQuery CSS selectors. No patches are available for this issue. | |||||
| CVE-2021-32816 | 1 Protonmail | 1 Protonmail | 2024-11-21 | 5.0 MEDIUM | 6.5 MEDIUM |
| ProtonMail Web Client is the official AngularJS web client for the ProtonMail secure email service. ProtonMail Web Client before version 3.16.60 has a regular expression denial-of-service vulnerability. This was fixed in commit 6687fb.

| CVE-2021-32763 | 1 Openproject | 1 Openproject | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| OpenProject is open-source, web-based project management software. In versions prior to 11.3.3, the `MessagesController` class of OpenProject has a `quote` method that implements the logic behind the Quote button in the discussion forums, and it uses a regex to strip `<pre>` tags from the message being quoted. The `(.|\s)` part can match a space character in two ways, so an unterminated `<pre>` tag containing `n` spaces causes Ruby's regex engine to backtrack to try 2<sup>n</sup> states in the NFA. This will result in a Regular Expression Denial of Service. The issue is fixed in OpenProject 11.3.3. As a workaround, one may install the patch manually. | |||||
| CVE-2021-32740 | 2 Addressable Project, Fedoraproject | 2 Addressable, Fedora | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. An uncontrolled resource consumption vulnerability exists after version 2.3.0 through version 2.7.0. Within the URI template implementation in Addressable, a maliciously crafted template may result in uncontrolled resource consumption, leading to denial of service when matched against a URI. In typical usage, templates would not normally be read from untrusted user input, but nonetheless, no previous security advisory for Addressable has cautioned against doing this. Users of the parsing capabilities in Addressable but not the URI template capabilities are unaffected. The vulnerability is patched in version 2.8.0. As a workaround, only create Template objects from trusted sources that have been validated not to produce catastrophic backtracking. | |||||
| CVE-2021-32723 | 2 Oracle, Prismjs | 2 Application Express, Prism | 2024-11-21 | 4.3 MEDIUM | 7.4 HIGH |
| Prism is a syntax highlighting library. Some languages before 1.24.0 are vulnerable to Regular Expression Denial of Service (ReDoS). When Prism is used to highlight untrusted (user-given) text, an attacker can craft a string that will take a very very long time to highlight. This problem has been fixed in Prism v1.24. As a workaround, do not use ASCIIDoc or ERB to highlight untrusted text. Other languages are not affected and can be used to highlight untrusted text. | |||||
| CVE-2021-32722 | 1 Miraheze | 1 Globalnewfiles | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| GlobalNewFiles is a mediawiki extension. Versions prior to 48be7adb70568e20e961ea1cb70904454a671b1d are affected by an uncontrolled resource consumption vulnerability. A large amount of page moves within a short space of time could overwhelm Database servers due to improper handling of load balancing and a lack of an appropriate index. As a workaround, one may avoid use of the extension unless additional rate limit at the MediaWiki level or via PoolCounter / MySQL is enabled. A patch is available in version 48be7adb70568e20e961ea1cb70904454a671b1d. | |||||
| CVE-2021-32699 | 1 Pterodactyl | 1 Wings | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| Wings is the control plane software for the open source Pterodactyl game management system. All versions of Pterodactyl Wings prior to `1.4.4` are vulnerable to system resource exhaustion due to improper container process limits being defined. A malicious user can consume more resources than intended and cause downstream impacts to other clients on the same hardware, eventually causing the physical server to stop responding. Users should upgrade to `1.4.4` to mitigate the issue. There is no non-code based workaround for impacted versions of the software. Users running customized versions of this software can manually set a PID limit for containers created. | |||||
| CVE-2021-32657 | 1 Nextcloud | 1 Nextcloud Server | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| Nextcloud Server is a Nextcloud package that handles data storage. In versions of Nextcloud Server prior to 10.0.11, 20.0.10, and 21.0.2, a malicious user may be able to break the user administration page. This would disallow administrators to administrate users on the Nextcloud instance. The vulnerability is fixed in versions 19.0.11, 20.0.10, and 21.0.2. As a workaround, administrators can use the OCC command line tool to administrate the Nextcloud users. | |||||
| CVE-2021-32640 | 2 Netapp, Ws Project | 2 E-series Performance Analyzer, Ws | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| ws is an open source WebSocket client and server library for Node.js. A specially crafted value of the `Sec-Websocket-Protocol` header can be used to significantly slow down a ws server. The vulnerability has been fixed in ws@7.4.6 (https://github.com/websockets/ws/commit/00c425ec77993773d823f018f64a5c44e17023ff). In vulnerable versions of ws, the issue can be mitigated by reducing the maximum allowed length of the request headers using the [`--max-http-header-size=size`](https://nodejs.org/api/cli.html#cli_max_http_header_size_size) and/or the [`maxHeaderSize`](https://nodejs.org/api/http.html#http_http_createserver_options_requestlistener) options. | |||||
| CVE-2021-32617 | 2 Exiv2, Fedoraproject | 2 Exiv2, Fedora | 2024-11-21 | 4.3 MEDIUM | 4.7 MEDIUM |
| Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An inefficient algorithm (quadratic complexity) was found in Exiv2 versions v0.27.3 and earlier. The inefficient algorithm is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4. Note that this bug is only triggered when _writing_ the metadata, which is a less frequently used Exiv2 operation than _reading_ the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `rm`. | |||||
