### Impact XWiki Crypto API will generate X509 certificates signed by default using SHA1 with RSA, which is not considered safe anymore for use in certificate signatures, due to the risk of collisions with SHA1. Note that this API is never used in XWiki Standard but it might be used in some extensions of XWiki. ### Patches The problem has been patched in XWiki version 13.10.6, 14.3.1 and 14.4-rc-1. Since then, the Crypto API will generate X509 certificates signed by default using SHA256 with RSA. ### Workarounds Administrators are advised to upgrade their XWiki installation to one of the patched versions. If the upgrade is not possible, it is possible to patch the module xwiki-platform-crypto in a local installation by applying the change exposed in https://github.com/xwiki/xwiki-platform/commit/26728f3f23658288683667a5182a916c7ecefc52 and re-compiling the module. ### References https://jira.xwiki.org/browse/XWIKI-19676 https://github.com/openssl/openssl/blob/master/CHANGES.md?plain...

### Impact A vulnerability was found in Argo CD that allows an attacker to spoof error messages on the login screen when SSO is enabled. In order to exploit this vulnerability, an attacker would have to trick the victim to visit a specially crafted URL which contains the message to be displayed. As far as the research of the Argo CD team concluded, it is not possible to specify any active content (e.g. Javascript) or other HTML fragments (e.g. clickable links) in the spoofed message. ### Patched versions A patch for this vulnerability has been released in the following Argo CD versions: * v2.3.4 * v2.2.9 * v2.1.15 ### Workarounds No workaround available. #### Mitigations It is advised to update to an Argo CD version containing a fix for this issue (see *Patched versions* above). ### Credits This vulnerability was discovered by Naufal Septiadi (<naufal@horangi.com>) and reported to us in a responsible way. ### For more information <!-- Use only one of the paragraphs below...

### Summary Nokogiri `< v1.13.6` does not type-check all inputs into the XML and HTML4 SAX parsers. For CRuby users, this may allow specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. ### Severity The Nokogiri maintainers have evaluated this as **High 8.2** (CVSS3.1). ### Mitigation CRuby users should upgrade to Nokogiri `>= 1.13.6`. JRuby users are not affected. ### Workarounds To avoid this vulnerability in affected applications, ensure the untrusted input is a `String` by calling `#to_s` or equivalent. ### Credit This vulnerability was responsibly reported by @agustingianni and the Github Security Lab.

### Impact All unpatched versions of Argo CD starting with v0.7.0 are vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive files from Argo CD's repo-server. A malicious Argo CD user with write access for a repository which is (or may be) used in a directory-type Application may commit a symlink which points to an out-of-bounds file. * If the target file is a valid JSON or YAML manifest file, and the resource is allowed in the Application, the attacker can read the contents of that manifest file. (In versions <2.3.2, <2.2.8, and <2.1.14, the attacker may read the files contents even if the resource is _not_ allowed in the Application). * If the target file is valid JSON but is _not_ a manifest file, the attacker may read the contents of the file. * If the target file is not valid JSON or YAML, the attacker may read partial file contents (usually just the first character of the file). Sensitive files which could be leaked in...

Hawk is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with partial cryptographic verification of the request and response, covering the HTTP method, request URI, host, and optionally the request payload. Hawk used a regular expression to parse `Host` HTTP header (`Hawk.utils.parseHost()`), which was subject to regular expression DoS attack - meaning each added character in the attacker's input increases the computation time exponentially. `parseHost()` was patched in `9.0.1` to use built-in `URL` class to parse hostname instead.`Hawk.authenticate()` accepts `options` argument. If that contains `host` and `port`, those would be used instead of a call to `utils.parseHost()`.

matrix-appservice-irc provides an IRC bridge for Matrix. The vulnerability in node-irc allows an attacker to manipulate a Matrix user into executing IRC commands by having them reply to a maliciously crafted message. The vulnerability has been patched in matrix-appservice-irc 0.33.2. In terms of a workaround, users should refrain from replying to messages from untrusted participants in IRC-bridged Matrix rooms.

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. * The attacker creates a workflow that produces a HTML artifact that contains a HTML file that contains a script which uses XHR calls to interact with the Argo Server API. * The attacker emails the deep-link to the artifact to their victim. The victim opens the link, the script starts running. As the script has access to the Argo Server API (as the victim), so may do the following (if the victim may): * Read information about the victim’s workflows. * Create or delete workflows. Notes: * The attacker must be an insider: they must have access to the same cluster as the victim and must already be able to run their own workflows. * The attacker must have an understanding of the victim’s system. They won’t be able to repeatedly probe due to the social engineering aspect. * The attacker is likely leave an audit trail. We have seen no evidence of this in the wild. While th...

### Impact Untrusted users can inject malicious code into the canonical tag, which is then executed on the web page (front end). ### Patches Update to Contao 4.13.3. ### Workarounds Disable canonical tags in the root page settings. ### References https://contao.org/en/security-advisories/cross-site-scripting-via-canonical-url.html ### For more information If you have any questions or comments about this advisory, open an issue in [contao/contao](https://github.com/contao/contao/issues/new/choose).

The kustomize-controller enables the use of Kustomize’s functionality when applying Kubernetes declarative state onto a cluster. A malicious user can use a specially crafted `kustomization.yaml` to cause Denial of Service at controller level. In multi-tenancy deployments this can lead to multiple tenants not being able to apply their Kustomizations until the malicious `kustomization.yaml` is removed and the controller restarted. ### Impact Within the affected versions, users with write access to a Flux source are able to craft a malicious `kustomization.yaml` file which causes the controller to enter an endless loop. ### Patches This vulnerability was fixed in kustomize-controller v0.24.0 and included in flux2 v0.29.0 released on 2022-04-20. The changes introduce better handling of Kustomization files blocking references that could lead to endless loops. ### Credits The Flux engineering team found and patched this vulnerability. ### For more information If you have any questio...

### Impact There is a potential Cross-Site Scripting (XSS) vulnerability where an arbitrary user is able to execute scripts on pages that are built with Hydrogen. This affects all versions of Hydrogen starting from version 0.10.0 to 0.18.0. This vulnerability is exploitable in applications whose hydrating data is user controlled. ### Patches All Hydrogen users should upgrade their project to v0.19.0. ### Workarounds There is no current workaround, and users should update as soon as possible. Additionally, the Content Security Policy is not an effective mitigation for this vulnerability. ### References GitHub: [Hydrogen v0.19.0](https://github.com/Shopify/hydrogen/releases/tag/%40shopify/hydrogen%400.19.0) Fix PR: https://github.com/Shopify/hydrogen/pull/1272 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Shopify/hydrogen](https://github.com/Shopify/hydrogen/issues/new/choose)
