Vulnerabilities

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.3.0, a Markdown document containing many repeated or distinct reference-link definitions causes quadratic work in src/mistune/block_parser.py and the ref_links environment dictionary handling, allowing denial of service through CPU exhaustion. This issue is fixed in version 3.3.0.

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.2.1, the Image directive plugin validates the :width: and :height: options with a regex compiled as _num_re = re.compile(r"^\d+(?:\.\d*)?"). When the validated value is not a plain integer, render_block_image() inserts it directly into a style="width:...;" or style="height:...;" attribute. Because the value was accepted by the prefix-only regex, any CSS after the leading digits reaches the style= attribute verbatim and without escaping. This vulnerability is fixed in 3.2.1.

CVE-2026-45321 is a supply chain compromise in which 84 malicious versions across 42 @tanstack/* npm packages (including @tanstack/react-router, @tanstack/react-start, @tanstack/history, and related router/start packages) were published to the npm registry on 2026-05-11 between roughly 19:20 and 19:26 UTC, authenticated through TanStack's legitimate GitHub Actions OIDC trusted-publisher binding. The attacker chained three known weakness classes — a pull_request_target 'Pwn Request' misconfiguration, GitHub Actions cache poisoning across the fork-to-base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — allowing publication under a trusted identity without modifying the publish workflow. Each affected package received exactly two malicious versions carrying credential-stealing malware, so developers, CI pipelines, or downstream builds that installed them could have npm, GitHub, and cloud credentials extracted; related reporting (FBI, StepSecurity) links the campaign to stolen cloud credentials and a self-spreading 'Mini Shai-Hulud' worm that also hit packages in other ecosystems such as Mistral AI and Guardrails AI. Exposure is limited to consumers who installed the two malicious versions published per package during the exposure window; other users of these widely deployed libraries were not affected by the malicious publishes. Exploitation is confirmed in the wild: the issue was added to CISA's Known Exploited Vulnerabilities catalog on 2026-05-27 with known ransomware use, and EPSS estimates a 2.3% probability of exploitation in the next 30 days (83rd percentile).

Do: Audit lockfiles and CI logs for the affected @tanstack/* packages' versions published during the 2026-05-11 ~19:20-19:26 UTC window; if found, reinstall from clean versions per the TanStack postmortem (tanstack.com/blog/npm-supply-chain-compromise-postmortem) and rotate exposed credentials (npm tokens, GitHub PATs/secrets, cloud keys), treating any cached CI artifacts as suspect. Apply mitigations per vendor instructions and CISA BOD 22-01 guidance for cloud services, or discontinue use if mitigations are unavailable, and remediate the underlying CI weaknesses (pull_request_target handling, Actions cache hygiene, and OIDC token handling) to prevent recurrence.

The Mambo Importer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0 via deserialization of untrusted input via the $data parameter in the fImportMenu function. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
