|---|---|---|---|---|---|
| CVE-2025-5020 | 1 Mozilla | 1 Firefox | 2025-06-13 | N/A | 4.3 MEDIUM |
| Opening maliciously-crafted URLs in Firefox from other apps such as Safari could have allowed attackers to spoof website addresses if the URLs utilized non-HTTP schemes used internally by the Firefox iOS client This vulnerability affects Firefox for iOS < 139. | |||||
| CVE-2025-2817 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-13 | N/A | 8.8 HIGH |
| Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird < 128.10. | |||||
| CVE-2025-3523 | 1 Mozilla | 1 Thunderbird | 2025-06-13 | 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 affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2. | |||||
| CVE-2023-5758 | 1 Mozilla | 1 Firefox | 2025-06-12 | N/A | 6.1 MEDIUM |
| When opening a page in reader mode, the redirect URL could have caused attacker-controlled script to execute in a reflected Cross-Site Scripting (XSS) attack. This vulnerability affects Firefox for iOS < 119. | |||||
| CVE-2024-0748 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 4.3 MEDIUM |
| A compromised content process could have updated the document URI. This could have allowed an attacker to set an arbitrary URI in the address bar or history. This vulnerability affects Firefox < 122. | |||||
| CVE-2025-5268 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-11 | N/A | 6.5 MEDIUM |
| Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10.

This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-5272 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-11 | N/A | 7.3 HIGH |
| Memory safety bugs present in Firefox 138 and Thunderbird 138. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 139 and Thunderbird < 139. | |||||
| CVE-2025-5271 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 6.5 MEDIUM |
| Previewing a response in Devtools ignored CSP headers, which could have allowed content injection attacks. This vulnerability affects Firefox < 139 and Thunderbird < 139. | |||||
| CVE-2025-5270 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 7.5 HIGH |

| CVE-2025-5269 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-11 | N/A | 6.5 MEDIUM |
| Memory safety bug present in Firefox ESR 128.10, and Thunderbird 128.10. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 128.11 and Thunderbird < 128.11. | |||||
| CVE-2025-5267 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 5.4 MEDIUM |
| A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-5266 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 6.5 MEDIUM |
| Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-5265 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 4.8 MEDIUM |
| Due to insufficient escaping of the ampersand character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. *This bug only affects Firefox for Windows. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-5264 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 4.8 MEDIUM |
| Due to insufficient escaping of the newline character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-5263 | 1 Mozilla | 1 Firefox | 2025-06-11 | N/A | 4.3 MEDIUM |
| Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2023-5388 | 2 Debian, Mozilla | 3 Debian Linux, Firefox, Thunderbird | 2025-06-09 | N/A | 6.5 MEDIUM |
| NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9. | |||||
| CVE-2024-0753 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2025-06-07 | N/A | 6.5 MEDIUM |
| In specific HSTS configurations an attacker could have bypassed HSTS on a subdomain. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7. | |||||
| CVE-2025-3875 | 1 Mozilla | 1 Thunderbird | 2025-06-05 | 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 affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
| CVE-2025-3909 | 1 Mozilla | 1 Thunderbird | 2025-06-05 | N/A | 6.5 MEDIUM |
| 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 affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
| CVE-2025-3932 | 1 Mozilla | 1 Thunderbird | 2025-06-05 | 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 affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
