### Impact Anyone who has view rights on the `Calendar.JSONService` page, including guest users can exploit this vulnerability by accessing database info, with the exception of passwords. ### Workarounds Remove the `Calendar.JSONService` page. This will however break some functionalities. ### References Jira issue: * [FULLCAL-82: Calendar.JSONService exposes emails of all users](https://jira.xwiki.org/browse/FULLCAL-82) ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org)

A cross-site scripting (XSS) vulnerabilities was identified in October CMS backend configuration forms: - **Editor Settings Markup Styles** A user with the `Global Editor Settings` permission could inject malicious HTML/JS into the stylesheet input at *Settings → Editor Settings → Markup Styles*. A specially crafted input could break out of the intended `<style>` context, allowing arbitrary script execution across backend pages for all users. --- ### Impact - Persistent XSS across the backend interface. - Exploitable by lower-privileged accounts with the above permissions. - Potential consequences include privilege escalation, session hijacking, and execution of unauthorized actions in victim sessions. --- ### Patches The vulnerability has been patched in **v4.0.12** and **v3.7.13**. Stylesheet inputs are now sanitized to prevent injection of arbitrary HTML/JS. All users are strongly encouraged to upgrade to the latest patched version. --- ### Workarounds I...

Chinese-speaking threat actors are suspected to have leveraged a compromised SonicWall VPN appliance as an initial access vector to deploy a VMware ESXi exploit that may have been developed as far back as February 2024. Cybersecurity firm Huntress, which observed the activity in December 2025 and stopped it before it could progress to the final stage, said it may have resulted in a ransomware

After years of security failures and partner-spying marketing, pcTattletale’s founder has pleaded guilty in a rare US federal stalkerware case.

Russian state-sponsored threat actors have been linked to a fresh set of credential harvesting attacks targeting individuals associated with a Turkish energy and nuclear research agency, as well as staff affiliated with a European think tank and organizations in North Macedonia and Uzbekistan. The activity has been attributed to APT28 (aka BlueDelta), which was attributed to a "sustained"

Fastjson before 1.2.48 mishandles autoType because, when an `@type` key is in a JSON document, and the value of that key is the name of a Java class, there may be calls to certain public methods of that class. Depending on the behavior of those methods, there may be JNDI injection with an attacker-supplied payload located elsewhere in that JSON document. This was exploited in the wild in 2023 through 2025. NOTE: this issue exists because of an incomplete fix for CVE-2017-18349. Also, a later bypass is covered by CVE-2022-25845.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday said it's retiring 10 emergency directives (Eds) that were issued between 2019 and 2024. The list of the directives now considered closed is as follows - ED 19-01: Mitigate DNS Infrastructure Tampering ED 20-02: Mitigate Windows Vulnerabilities from January 2020 Patch Tuesday ED 20-03: Mitigate Windows DNS Server

The U.S. Federal Bureau of Investigation (FBI) on Thursday released an advisory warning of North Korean state-sponsored threat actors leveraging malicious QR codes in spear-phishing campaigns targeting entities in the country. "As of 2025, Kimsuky actors have targeted think tanks, academic institutions, and both U.S. and foreign government entities with embedded malicious Quick Response (QR)

The Security Labs team at Snyk is reporting a security issue affecting Authlib, which was identified during a recent research project. A vulnerability has been identified that can result in a 1-click Account Takeover in applications that use the Authlib library. (5.7 CVSS v3: AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N) **Description** Cache-backed state/request-token storage is not tied to the initiating user session, so CSRF is possible for any attacker that has a valid state (easily obtainable via an attacker-initiated authentication flow). When a cache is supplied to the OAuth client registry, `FrameworkIntegration.set_state_data` writes the entire state blob under `_state_{app}_{state},` and `get_state_data` ignores the caller’s session altogether. \[1\]\[2\] ```py def _get_cache_data(self, key): value = self.cache.get(key) if not value: return None try: return json.loads(value) except (TypeError, ValueError): ret...

### Summary The fix [here](https://github.com/vllm-project/vllm/pull/27204) for CVE-2025-62164 is not sufficient. The fix only disables prompt embeds by default rather than addressing the root cause, so the DoS vulnerability remains when the feature is enabled. ### Details vLLM's pending change attempts to fix the root cause, which is the missing sparse tensor validation. PyTorch (~v2.0) disables sparse tensor validation (specifically, sparse tensor invariants checks) by default for performance reasons. vLLM is adding the sparse tensor validation to ensure indices are valid, non-negative, and within bounds. These checks help catch malformed tensors. ### PoC NA ### Impact Current fix only added a flag to disable/enable prompt embeds, so by default, prompt embeds feature is disabled in vLLM, which stops DoS attacks through the embeddings. However, It doesn’t address the problem when the flag is enabled and there is still potential for DoS attacks. ### Changes * https://github.co...
