| CVE-2026-0818 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 4.3 MEDIUM |
| When a user explicitly requested Thunderbird to decrypt an inline OpenPGP message that was embedded in a text section of an email that was formatted and styled with HTML and CSS, then the decrypted contents were rendered in a context in which the CSS styles from the outer messages were active. If the user had additionally allowed loading of the remote content referenced by the outer email message, and the email was crafted by the sender using a combination of CSS rules and fonts and animations, then it was possible to extract the secret contents of the email. This vulnerability was fixed in Thunderbird 147.0.1 and Thunderbird 140.7.1. | |||||
| CVE-2025-6703 | 1 Mozilla | 1 Neqo | 2026-06-17 | N/A | 6.5 MEDIUM |
| Improper Input Validation vulnerability in Mozilla neqo leads to an unexploitable crash..This issue affects neqo: from 0.4.24 through 0.13.2. | |||||
| CVE-2025-5986 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger. Viewing the email in HTML mode is enough to load external content. This vulnerability was fixed in Thunderbird 128.11.1 and Thunderbird 139.0.2. | |||||
| CVE-2025-5687 | 1 Mozilla | 1 Vpn | 2026-06-17 | N/A | 7.8 HIGH |
| A vulnerability in Mozilla VPN on macOS allows privilege escalation from a normal user to root. *This bug only affects Mozilla VPN on macOS. Other operating systems are unaffected.*. This vulnerability was fixed in Mozilla VPN 2.28.0 (macOS). | |||||
| CVE-2025-5262 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 7.5 HIGH |
| A double-free could have occurred in `vpx_codec_enc_init_multi` after a failed allocation when initializing the encoder for WebRTC. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 139 and Thunderbird < 128.11. | |||||
| CVE-2025-55033 | 1 Mozilla | 1 Firefox Focus | 2026-06-17 | N/A | 6.1 MEDIUM |
| Dragging JavaScript links to the URL bar in Focus for iOS could be utilized to run malicious scripts, potentially resulting in XSS attacks. This vulnerability was fixed in Focus for iOS 142. | |||||
| CVE-2025-55032 | 1 Mozilla | 1 Firefox Focus | 2026-06-17 | N/A | 6.1 MEDIUM |
| Focus for iOS would not respect a Content-Disposition header of type Attachment and would incorrectly display the content inline, potentially allowing for XSS attacks. This vulnerability was fixed in Focus for iOS 142. | |||||
| CVE-2025-3932 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| It was possible to craft an email that showed a tracking link as an attachment. If the user attempted to open the attachment, Thunderbird automatically accessed the link. The configuration to block remote content did not prevent that. Thunderbird has been fixed to no longer allow access to web pages listed in the X-Mozilla-External-Attachment-URL header of an email. This vulnerability was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1. | |||||
| CVE-2025-3909 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 8.1 HIGH |
| Thunderbird's handling of the X-Mozilla-External-Attachment-URL header can be exploited to execute JavaScript in the file:/// context. By crafting a nested email attachment (message/rfc822) and setting its content type to application/pdf, Thunderbird may incorrectly render it as HTML when opened, allowing the embedded JavaScript to run without requiring a file download. This behavior relies on Thunderbird auto-saving the attachment to /tmp and linking to it via the file:/// protocol, potentially enabling JavaScript execution as part of the HTML. This vulnerability was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1. | |||||
| CVE-2025-3875 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 7.5 HIGH |
| Thunderbird parses addresses in a way that can allow sender spoofing in case the server allows an invalid From address to be used. For example, if the From header contains an (invalid) value "Spoofed Name ", Thunderbird treats spoofed@example.com as the actual address. This vulnerability was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1. | |||||
| CVE-2025-3859 | 1 Mozilla | 1 Firefox Focus | 2026-06-17 | N/A | 6.1 MEDIUM |
| Websites directing users to long URLs that caused eliding to occur in the location view could leverage the truncating behavior to potentially trick users into thinking they were on a different webpage. This vulnerability was fixed in Focus 138. | |||||
| CVE-2025-3523 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 6.4 MEDIUM |
| When an email contains multiple attachments with external links via the X-Mozilla-External-Attachment-URL header, only the last link is shown when hovering over any attachment. Although the correct link is used on click, the misleading hover text could trick users into downloading content from untrusted sources. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2. | |||||
| CVE-2025-3522 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 6.3 MEDIUM |
| Thunderbird processes the X-Mozilla-External-Attachment-URL header to handle attachments which can be hosted externally. When an email is opened, Thunderbird accesses the specified URL to determine file size, and navigates to it when the user clicks the attachment. Because the URL is not validated or sanitized, it can reference internal resources like chrome:// or SMB share file:// links, potentially leading to hashed Windows credential leakage and opening the door to more serious security issues. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2. | |||||
| CVE-2025-2830 | 1 Mozilla | 1 Thunderbird | 2026-06-17 | N/A | 6.3 MEDIUM |
| By crafting a malformed file name for an attachment in a multipart message, an attacker can trick Thunderbird into including a directory listing of /tmp when the message is forwarded or edited as a new message. This vulnerability could allow attackers to disclose sensitive information from the victim's system. This vulnerability is not limited to Linux; similar behavior has been observed on Windows as well. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2. | |||||
