On Linux the sccache client can execute arbitrary code with the privileges of a local sccache server, by preloading the code in a shared library passed to LD_PRELOAD. If the server is run as root (which is the default when installing the snap package https://snapcraft.io/sccache ), this means a user running the sccache client can get root privileges.

Nov 26, 2024Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') vulnerability in Mozilla Convict.CVE-2023-0163 · Computers, phones & browsers · Mozilla · reported by security@mozilla.orgHigh 8.4
Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') vulnerability in Mozilla Convict. This allows an attacker to inject attributes that are used in other components, or to override existing attributes with ones that have incompatible type, which may lead to a crash. The main use case of Convict is for handling server-side configurations written by the admins owning the servers, and not random users. So it's unlikely that an admin would deliberately sabotage their own server. Still, a situation can happen where an admin not knowledgeable about JavaScript could be tricked by an attacker into writing the malicious JavaScript code into some config files. This issue affects Convict: before 6.2.4.

Nov 13, 2024macro-pdfviewer is a PDF Viewer Macro for XWiki using Mozilla pdf.js.CVE-2024-52298 · Other software · xwikisas · reported by GitHubHigh 7.5
macro-pdfviewer is a PDF Viewer Macro for XWiki using Mozilla pdf.js. The PDF Viewer macro allows an attacker to view any attachment using the "Delegate my view right" feature as long as the attacker can view a page whose last author has access to the attachment. For this, the attacker only needs to provide the reference to a PDF file to the macro. To obtain the reference of the desired attachment, the attacker can access the Page Index, Attachments tab. Even if the UI shows N/A, the user can inspect the page and check the HTTP request that fetches the live data entries. The attachment URL is available in the returned JSON for all attachments, including protected ones and allows getting the necessary values. This vulnerability is fixed in version 2.5.6.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
