-
CVE-2026-109810
SAP NetWeaver Application Server Java (Web Dynpro Java) does not sufficiently validate certain request parameters used to resolve styling resources in the application. An unauthenticated attacker could craft a malicious link that, when clicked by an authenticated victim, causes the victim's browser to load attacker-controlled styling content within the trusted application context. Successful exploitation could allow the attacker to redress the trusted user interface for phishing purposes and exfiltrate limited web page content, resulting in a low impact on confidentiality and integrity. There is no impact on availability.

-
CVE-2026-118046
The JS Help Desk – AI-Powered Support & Ticketing System plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'jsticket_message' parameter in all versions up to, and including, 5.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload fires specifically when an administrator or agent opens the affected ticket and the page initializes VenoBox, which reads the browser-decoded data-title attribute and passes it to jQuery .html(), making routine ticket review the trigger condition.
-
CVE-2026-119098
The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'answer[]' parameter in all versions up to, and including, 10.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the attacker to be enrolled as a student in a course containing a Content-type quiz question; the injected payload executes in the administrator's browser session during the normal grading workflow when 'Start a Review' is clicked on the affected attempt.
-
CVE-2026-125395
Ampache before 8.4.0 contains a stored cross-site scripting vulnerability that allows users with upload rights to inject script through unescaped song lyrics in LyricsView.php getLyrics() and show_lyrics.inc.php. Attackers can upload a song whose lyrics ID3 tag contains HTML and script to execute code in the browser of any user viewing the lyrics.
-
CVE-2026-124902
Same-origin policy bypass due to race condition in the Audio/Video component. This vulnerability was fixed in Firefox 160, Firefox ESR 115.45, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7.
-
CVE-2026-124874
Same-origin policy bypass in the Networking: HTTP component. This vulnerability was fixed in Firefox 160, Firefox ESR 115.45, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7.
-
CVE-2026-126134
Thunderbird allowed feed subscriptions to file: URLs that point to a network share. If a user was tricked into subscribing to such a URL, Thunderbird connected to the attacker's server when fetching the feed. Windows then sent the user's NTLM credentials to that server. This bug only affects Thunderbird on Windows. Other operating systems are unaffected. This vulnerability was fixed in Thunderbird 160 and Thunderbird 153.7.
-
CVE-2026-120016
SAP NetWeaver Visual Composer does not perform sufficient input validation and output encoding on certain request data. An unauthenticated attacker could craft a malicious link containing specially crafted input. If a victim clicks the link, the injected script executes in the victim's browser within the context of the affected application. This results in a low impact on confidentiality and integrity. There is no impact on availability.
-
CVE-2026-124928
Mitigation bypass in the SVG component. This vulnerability was fixed in Firefox 160 and Thunderbird 160.
-
CVE-2026-124910
Mitigation bypass in the WebExtensions component. This vulnerability was fixed in Firefox 160, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7.
-
CVE-2026-126135
If an attacker was able to perform a man-in-the-middle attack on an SMTP or POP3 server connection using STARTTLS, the attacker could inject server responses before the TLS handshake completed. Thunderbird would process these responses after the handshake, as if they had been received from the server over the encrypted connection. This could be used to make Thunderbird report a different outcome for sending or fetching mail, and to show attacker-controlled text in error messages. The encrypted connection itself was not compromised, and credentials were not exposed. Connections using SSL/TLS instead of STARTTLS were not affected. This vulnerability was fixed in Thunderbird 160 and Thunderbird 153.7.
-
CVE-2026-124905
Sandbox escape in the DOM: Navigation component. This vulnerability was fixed in Firefox 160, Firefox ESR 115.45, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7.

-
CVE-2026-125358
Universal-modder before commit e88f6876745427321eb755ebc98276063a962d8a contains a missing WebSocket Origin validation vulnerability in the HostLink class of its passthrough example mods that allows remote attackers to execute Minecraft commands. Any web page open in the player's browser can connect cross-site to the unauthenticated loopback WebSocket and send cmd messages that WorldBridge.command() runs with operator authority.
-
CVE-2026-126132
When a message was forwarded inline, edited as new, or had an attachment dragged into a compose window, a specially crafted link attachment (a .desktop file on Linux, or a .url or .lnk file on Windows) was replaced with the content of the file or URL it pointed to when the message was saved or sent. This could disclose local files, or content from the user's network, to the message recipients or to the mail provider. This bug only affects Thunderbird on Linux and Windows. Other operating systems are unaffected. This vulnerability was fixed in Thunderbird 160 and Thunderbird 153.7.
