The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them.<br>*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.

Windows Compressed Folder Tampering Vulnerability

Insufficient validation of untrusted input in Intents in Google Chrome on Android prior to 104.0.5112.101 allowed a remote attacker to arbitrarily browse to a malicious website via a crafted HTML page.

Type confusion in extensions JavaScript bindings in Google Chrome prior to 60.0.3112.78 for Mac, Windows, Linux, and Android allowed a remote attacker to potentially maliciously modify objects via a crafted HTML page.

When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1.

Windows Print Spooler Spoofing Vulnerability

Microsoft Bing Search Spoofing Vulnerability

IBM Jazz for Service Management 1.1.3.10 and IBM Tivoli Netcool/OMNIbus_GUI is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts. IBM X-Force ID: 204341.

Acrobat Reader DC versions versions 2020.013.20074 (and earlier), 2020.001.30018 (and earlier) and 2017.011.30188 (and earlier) are missing support for an integrity check. An unauthenticated attacker could leverage this vulnerability to modify content in a certified PDF without invalidating the certification. Exploitation of this issue requires user interaction in that a victim must open the tampered file.

Inappropriate use of www mismatch redirects in browser navigation in Google Chrome prior to 61.0.3163.79 for Mac, Windows, and Linux, and 61.0.3163.81 for Android, allowed a remote attacker to potentially downgrade HTTPS requests to HTTP via a crafted HTML page. In other words, Chrome could transmit cleartext even though the user had entered an https URL, because of a misdesigned workaround for cases where the domain name in a URL almost matches the domain name in an X.509 server certificate (but differs in the initial "www." substring).

Insufficient policy enforcement in File System API in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to bypass filesystem restrictions via a crafted HTML page.

Windows HTML Platforms Security Feature Bypass Vulnerability

Windows Search Security Feature Bypass Vulnerability

Insufficient policy enforcement in DevTools in Google Chrome on Windows prior to 108.0.5359.71 allowed a remote attacker to bypass filesystem restrictions via a crafted HTML page. (Chromium security severity: Medium)

An elevation of privilege vulnerability exists when Visual Studio fails to properly validate hardlinks while extracting archived files, aka 'Visual Studio Elevation of Privilege Vulnerability'.

Microsoft Office Spoofing Vulnerability

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can use JavaScript to alter annotation content and subsequently clear the file's modification status via JavaScript interfaces. This circumvents digital signature verification by hiding document modifications, allowing an attacker to mislead users about the document's integrity and compromise the trustworthiness of signed PDFs.
