CVSS v3.1 |
| When a network error occurred during page load, the prior content could have remained in view with a blank URL bar. This could have been used to obfuscate a spoofed web site. This vulnerability affects Firefox < 126. |
| Memory safety bugs present in Firefox 125. 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 < 126. |
| The file scheme of URLs would be hidden, resulting in potential spoofing of a website's address in the location bar This vulnerability affects Focus for iOS < 126. |
| Opening Javascript links in a new tab via long-press in the Firefox iOS client could result in a malicious script spoofing the URL of the new tab. This vulnerability affects Firefox for iOS < 134. |
| Long hostnames in URLs could be leveraged to obscure the actual host of the website or spoof the website address This vulnerability affects Firefox for iOS < 134. |
| When redirecting to an invalid protocol scheme, an attacker could spoof the address bar.
*Note: This issue only affected Android operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 134. |
| Under certain circumstances, a user opt-in setting that Focus should require authentication before use could have been be bypassed. This vulnerability affects Firefox < 134. |
| When using an invalid protocol scheme, an attacker could spoof the address bar.
*Note: This issue only affected Android operating systems. Other operating systems are unaffected.*
*Note: This issue is a different issue from CVE-2025-0244. This vulnerability affects Firefox < 134. |
| Memory safety bugs present in Firefox 133 and Thunderbird 133. 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 < 134 and Thunderbird < 134. |
| Malicious websites may have been able to perform user intent confirmation through tapjacking. This could have led to users unknowingly approving the launch of external applications, potentially exposing them to underlying vulnerabilities. This vulnerability affects Firefox < 133 and Thunderbird < 133. |
| The executable file warning was not presented when downloading .library-ms files.
*Note: This issue only affected Windows operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5. |
| Scanning certain QR codes that included text with a website URL could allow the URL to be opened without presenting the user with a confirmation alert first This vulnerability affects Firefox for iOS < 136. |
| Memory safety bugs present in Firefox 135 and Thunderbird 135. 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 < 136 and Thunderbird < 136. |
| Malicious websites utilizing a server-side redirect to an internal error page could result in a spoofed website URL This vulnerability affects Firefox for iOS < 136. |
| A select option could partially obscure the confirmation prompt shown before launching external apps. This could be used to trick a user in to launching an external app unexpectedly.
*This issue only affects Android versions of Firefox.* This vulnerability affects Firefox < 136. |
| Mozilla Firefox before 1.5.0.7 and Thunderbird before 1.5.0.7 makes it easy for users to accept self-signed certificates for the auto-update mechanism, which might allow remote user-assisted attackers to use DNS spoofing to trick users into visiting a malicious site and accepting a malicious certificate for the Mozilla update site, which can then be used to install arbitrary code on the next update. |
| Heap-based buffer overflow in the UTF8ToNewUnicode function for Firefox before 1.0.1 and Mozilla before 1.7.6 might allow remote attackers to cause a denial of service (crash) or execute arbitrary code via invalid sequences in a UTF8 encoded string that result in a zero length value. |
| Race condition in the JavaScript garbage collection in Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 might allow remote attackers to execute arbitrary code by causing the garbage collector to delete a temporary variable while it is still being used during the creation of a new Function object. |
| Multiple "missing security checks" in Firefox before 1.0.3 allow remote attackers to inject arbitrary Javascript into privileged pages using the _search target of the Firefox sidebar. |
| Firefox before 1.0.3, Mozilla Suite before 1.7.7, and Netscape 7.2 allows remote attackers to replace existing search plugins with malicious ones using sidebar.addSearchEngine and the same filename as the target engine, which may not be displayed in the GUI, which could then be used to execute malicious script, aka "Firesearching 2." |
