Bugzilla 2.16.x before 2.16.1 does not properly filter apostrophes from an email address during account creation, which allows remote attackers to execute arbitrary SQL via a SQL injection attack.

Focus incorrectly truncated URLs towards the beginning instead of around the origin. This vulnerability affects Firefox < 141 and Thunderbird < 141.

Firefox ignored paths when checking the validity of navigations in a frame. This vulnerability affects Firefox < 141, Firefox ESR < 140.1, Thunderbird < 141, and Thunderbird < 140.1.

The `fetch()` API and navigation incorrectly shared the same cache, as the cache key did not include the optional headers `fetch()` may contain. Under the correct circumstances, an attacker may have been able to poison the local browser cache by priming it with a `fetch()` response controlled by the additional headers. Upon navigation to the same URL, the user would see the cached response instead of the expected response. This vulnerability affects Firefox < 123.

Bugzilla before 2.14 stores user passwords in plaintext and sends password requests in an email message, which could allow attackers to gain privileges.

Memory safety bugs present in Firefox 113. 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 < 114.

Memory safety bugs present in Firefox 113, Firefox ESR 102.11, and Thunderbird 102.12. 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 ESR < 102.12, Firefox < 114, and Thunderbird < 102.12.

A double-free issue could have occurred in `sec_pkcs7_decoder_start_decrypt()` when handling an error path. Under specific conditions, the same symmetric key could have been freed twice, potentially leading to memory corruption. This vulnerability affects Firefox < 133, Thunderbird < 133, Firefox ESR < 128.7, and Thunderbird < 128.7.

A flaw in handling fullscreen transitions may have inadvertently caused the application to become stuck in fullscreen mode when a modal dialog was opened during the transition. This issue left users unable to exit fullscreen mode using standard actions like pressing "Esc" or accessing right-click menus, resulting in a disrupted browsing experience until the browser is restarted. *This bug only affects the application when running on macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.

The XPCVariant::VariantDataToJS function in the XPCOM implementation in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 does not enforce intended restrictions on interaction between chrome privileged code and objects obtained from remote web sites, which allows remote attackers to execute arbitrary JavaScript with chrome privileges via unspecified method calls, related to "doubly-wrapped objects."

Unspecified vulnerability in Firefox and Thunderbird before 1.5.0.2, and SeaMonkey before 1.0.1, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown attack vectors related to DHTML. NOTE: due to the lack of sufficient public details from the vendor as of 20060413, it is unclear how CVE-2006-1529, CVE-2006-1530, CVE-2006-1531, and CVE-2006-1723 are different.

Bugzilla 2.19.3 through 2.20 does not properly handle "//" sequences in URLs when redirecting a user from the login form, which could cause it to generate a partial URL in a form action that causes the user's browser to send the form data to another domain.

Mozilla developers and community members Ronald Crane, Andrew McCreight, Randell Jesup and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112. 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 < 113.

This vulnerability affects Firefox < 132, Firefox ESR < 128.4, Thunderbird < 128.4, and Thunderbird < 132.

Stack-based buffer overflow in Mozilla Firefox allows remote attackers to execute arbitrary code via unspecified vectors involving JavaScript. NOTE: the vendor and original researchers have released a follow-up comment disputing the severity of this issue, in which the researcher states that "we mentioned that there was a previously known Firefox vulnerability that could result in a stack overflow ending up in remote code execution. However, the code we presented did not in fact do this... I have not succeeded in making this code do anything more than cause a crash and eat up system resources"

Bugzilla 3.2.1, 3.0.7, and 3.3.2, when running under mod_perl, calls the srand function at startup time, which causes Apache children to have the same seed and produce insufficiently random numbers for random tokens, which allows remote attackers to bypass cross-site request forgery (CSRF) protection mechanisms and conduct unauthorized activities as other users.

Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. 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 ESR < 45.6 and Firefox < 50.1.

The favicon functionality in Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to execute arbitrary code via a <LINK rel="icon"> tag with a javascript: URL in the href attribute, aka "Firelinking."

An issue was discovered in Bleach 2.1.x before 2.1.3. Attributes that have URI values weren't properly sanitized if the values contained character entities. Using character entities, it was possible to construct a URI value with a scheme that was not allowed that would slide through unsanitized.

Mozilla Firefox 0.9.2 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session. NOTE: it was later reported that 2.x is also affected.

The XPConnect component in Mozilla Firefox before 2.0.0.17 allows remote attackers to "pollute XPCNativeWrappers" and execute arbitrary code with chrome privileges via vectors related to a SCRIPT element.

Bugzilla 2.14 before 2.14.2, and 2.16 before 2.16rc2, does not properly handle URL-encoded field names that are generated by some browsers, which could cause certain fields to appear to be unset, which has the effect of removing group permissions on bugs when buglist.cgi is provided with the encoded field names.

Bugzilla 2.14 before 2.14.2, and 2.16 before 2.16rc2, may allow remote attackers to cause a denial of service or execute certain queries via a SQL injection attack on the sort order parameter to buglist.cgi.

Cross-site scripting vulnerabilities in Bugzilla 2.14 before 2.14.2, and 2.16 before 2.16rc2, could allow remote attackers to execute script as other Bugzilla users via the full name (real name) field, which is not properly quoted by editusers.cgi.

Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to bypass the protection mechanism for codebase principals and execute arbitrary script via the -moz-binding CSS property in a signed JAR file.

The nsXMLHttpRequest::NotifyEventListeners method in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to bypass the same-origin policy and execute arbitrary script via multiple listeners, which bypass the inner window check.

Bugzilla before 2.14 does not properly restrict access to confidential bugs, which could allow Bugzilla users to bypass viewing permissions via modified bug id parameters in (1) process_bug.cgi, (2) show_activity.cgi, (3) showvotes.cgi, (4) showdependencytree.cgi, (5) showdependencygraph.cgi, (6) showattachment.cgi, or (7) describecomponents.cgi.

WebExtensions with the "ActiveTab" permission are able to access frames hosted within the active tab even if the frames are cross-origin. Malicious extensions can inject frames from arbitrary origins into the loaded page and then interact with them, bypassing same-origin user expectations with this permission. This vulnerability affects Firefox < 58.
