Jsx-slack is a library for building JSON objects for Slack Block Kit surfaces from JSX.
It is also including an updated test case to confirm rendering multiple tags in `` with multibyte characters. jsx-slack v4.5.2 has updated regular expressions for escaping blockquote characters to prevent catastrophic backtracking. v4.5.1 passes the test against ASCII characters but misses the case of multibyte characters. If an attacker can put a lot of JSX elements into `` tag _with including multibyte characters_, an internal regular expression for escaping characters may consume an excessive amount of computing resources. The maintainers found the patch for CVE-2021-43838 in jsx-slack v4.5.1 is insufficient tfor protection from a Regular Expression Denial of Service (ReDoS) attack. Jsx-slack is a package for building JSON objects for Slack block kit surfaces from JSX. In the wazuh-slack active response script in Wazuh 4.2.x before 4.2.5, untrusted user agents are passed to a curl command line, potentially resulting in remote code execution. Gitlab's Slack integration is incorrectly validating user input and allows to craft malicious URLs that are sent to slack. The legacy Slack import feature in Mattermost version 6.7.0 and earlier fails to properly limit the sizes of imported files, which allows an authenticated attacker to crash the server by importing large files via the Slack import REST API.Īn issue has been discovered affecting GitLab versions prior to 14.4.5, between 14.5.0 and 14.5.3, and between 14.6.0 and 14.6.1. As a workaround, do not print/output requests and responses for OAuth and client configurations in logs. Stricter and more secure debug formatting was introduced in v0.41.0 for OAuth secret types to reduce the possibility of printing sensitive information in application logs. Prior to 0.41.0, it was possible for Slack OAuth client information to leak in application debug logs. Slack Morphism is an async client library for Rust. As a workaround, people who use Slack webhooks may disable or filter debug logs.
The problem is fixed in version 1.3.2 which redacts sensitive URLs for webhooks. Debug logs expose sensitive URLs for Slack webhooks that contain private information. Slack Morphism is a modern client library for Slack Web/Events API/Socket Mode and Block Kit. There are currently no recommended workarounds. OpenSearch 2.2.1+ contains the fix for this issue.
A potential SSRF issue in OpenSearch Notifications Plugin 2.2.0 and below could allow an existing privileged user to enumerate listening services or interact with configured resources via HTTP requests exceeding the Notification plugin's intended scope. OpenSearch Notifications is a notifications plugin for OpenSearch that enables other plugins to send notifications via Email, Slack, Amazon Chime, Custom web-hook etc channels.
