GHSA-c2pc-g5qf-rfrf: league/commonmark's quadratic complexity bugs may lead to a denial of service

### Impact Several polynomial time complexity issues in league/commonmark may lead to unbounded resource exhaustion and subsequent denial of service. Malicious users could trigger that inefficient code with carefully crafted Markdown inputs that are specifically designed to ensure the worst-case performance is reached. Sending multiple such requests in parallel could tie up all available CPU resources and/or PHP-FPM processes, leading to denial of service for legitimate users. ### Patches These vulnerabilities have been patched in version 2.6.0. All users on older versions are highly encouraged to upgrade as soon as possible. ### Workarounds If you cannot upgrade, you may be able to mitigate the issues by: - Setting very low `memory_limit` and `max_execution_time` PHP configurations to prevent runaway resource usage - Implementing rate-limiting, bot protection, or other approaches to reduce the risk of simultaneous bad requests hitting your site - Limiting the size of inputs f...

GHSA-xhw3-4j3m-hq53: Winter CMS Modules allows a sandbox bypass in Twig templates leading to data modification and deletion

### Impact Affected versions of Winter CMS allow users with access to the CMS templates sections that modify Twig files to bypass the sandbox placed on Twig files and modify resources such as theme customisation values or modify, or remove, templates in the theme even if not provided direct access via the permissions. As all objects passed through to Twig are references to the live objects, it is also possible to also manipulate model data if models are passed directly to Twig, including changing attributes or even removing records entirely. In most cases, this is unwanted behavior and potentially dangerous. To actively exploit this security issue, an attacker would need access to the Backend with a user account with any of the following permissions: - `cms.manage_layouts` - `cms.manage_pages` - `cms.manage_partials` The Winter CMS maintainers strongly recommend that these permissions only be reserved to trusted administrators and developers in general. ### Patches In order to mi...

GHSA-h97m-ww89-6jmq: `idna` accepts Punycode labels that do not produce any non-ASCII when decoded

`idna` 0.5.0 and earlier accepts Punycode labels that do not produce any non-ASCII output, which means that either ASCII labels or the empty root label can be masked such that they appear unequal without IDNA processing or when processed with a different implementation and equal when processed with `idna` 0.5.0 or earlier. Concretely, `example.org` and `xn--example-.org` become equal after processing by `idna` 0.5.0 or earlier. Also, `example.org.xn--` and `example.org.` become equal after processing by `idna` 0.5.0 or earlier. In applications using `idna` (but not in `idna` itself) this may be able to lead to privilege escalation when host name comparison is part of a privilege check and the behavior is combined with a client that resolves domains with such labels instead of treating them as errors that preclude DNS resolution / URL fetching and with the attacker managing to introduce a DNS entry (and TLS certificate) for an `xn--`-masked name that turns into the name of the target ...

GHSA-6vx4-v2jw-qwqh: Trix editor subject to XSS vulnerabilities on copy & paste

The Trix editor, in versions prior to 2.1.9 and 1.3.3, is vulnerable to XSS + mutation XSS attacks when pasting malicious code. ### Impact An attacker could trick a user to copy and paste malicious code that would execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed. ### Patches Update Recommendation: Users should upgrade to Trix editor version 2.1.9 or later, which uses [DOMPurify](https://github.com/cure53/DOMPurify) to sanitize the pasted content. If using Trix 1.x, upgrade to version 1.3.3 or later. ### Mitigations This is not really a workaround but something that should be considered in addition to upgrading to the patched version. If affected users can disallow browsers that don't support a Content Security Policy, then this would be an effective workaround for this and all XSS vulnerabilities. Set CSP policies such as script-src 'self' to ensure th...

GHSA-92qf-8gh3-gwcm: Apache Superset: Improper SQL authorisation, parse not checking for specific postgres functions

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Apache Superset. Specifically, certain engine-specific functions are not checked, which allows attackers to bypass Apache Superset's SQL authorization. This issue is a follow-up to CVE-2024-39887 with additional disallowed PostgreSQL functions now included: query_to_xml_and_xmlschema, table_to_xml, table_to_xml_and_xmlschema. This issue affects Apache Superset: <4.1.0. Users are recommended to upgrade to version 4.1.0, which fixes the issue or add these Postgres functions to the config set DISALLOWED_SQL_FUNCTIONS.
