CVE-2024-1557 1 Mozilla 1 Firefox 2026-06-17 N/A 8.1 HIGH
Memory safety bugs present in Firefox 122. 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 < 123.
CVE-2024-1556 1 Mozilla 1 Firefox 2026-06-17 N/A 6.5 MEDIUM
The incorrect object was checked for NULL in the built-in profiler, potentially leading to invalid memory access and undefined behavior. *Note:* This issue only affects the application when the profiler is running. This vulnerability affects Firefox < 123.
CVE-2024-1555 1 Mozilla 1 Firefox 2026-06-17 N/A 8.3 HIGH
When opening a website using the `firefox://` protocol handler, SameSite cookies were not properly respected. This vulnerability affects Firefox < 123.
CVE-2024-1554 1 Mozilla 1 Firefox 2026-06-17 N/A 9.8 CRITICAL
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.
CVE-2024-1553 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 8.1 HIGH
Memory safety bugs present in Firefox 122, Firefox ESR 115.7, and Thunderbird 115.7. 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 < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1552 3 Debian, Linux, Mozilla 4 Debian Linux, Linux Kernel, Firefox and 1 more 2026-06-17 N/A 7.5 HIGH
Incorrect code generation could have led to unexpected numeric conversions and potential undefined behavior.*Note:* This issue only affects 32-bit ARM devices. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1551 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.1 MEDIUM
Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker could control the Content-Type response header, as well as control part of the response body, they could inject Set-Cookie response headers that would have been honored by the browser. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1550 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.1 MEDIUM
A malicious website could have used a combination of exiting fullscreen mode and `requestPointerLock` to cause the user's mouse to be re-positioned unexpectedly, which could have led to user confusion and inadvertently granting permissions they did not intend to grant. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1549 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.1 MEDIUM
If a website set a large custom cursor, portions of the cursor could have overlapped with the permission dialog, potentially resulting in user confusion and unexpected granted permissions. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1548 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 4.3 MEDIUM
A website could have obscured the fullscreen notification by using a dropdown select input element. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1547 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
Through a series of API calls and redirects, an attacker-controlled alert dialog could have been displayed on another website (with the victim website's URL shown). This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-1546 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2026-06-17 N/A 7.5 HIGH
When storing and re-accessing data on a networking channel, the length of buffers may have been confused, resulting in an out-of-bounds memory read. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2024-11708 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
Missing thread synchronization primitives could have led to a data race on members of the PlaybackParams structure. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11706 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
A null pointer dereference may have inadvertently occurred in `pk12util`, and specifically in the `SEC_ASN1DecodeItem_Util` function, when handling malformed or improperly formatted input files. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11705 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 9.1 CRITICAL
`NSC_DeriveKey` inadvertently assumed that the `phKey` parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows `phKey` to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11704 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 9.8 CRITICAL
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.
CVE-2024-11703 1 Mozilla 1 Firefox 2026-06-17 N/A 5.7 MEDIUM
On Android, Firefox may have inadvertently allowed viewing saved passwords without the required device PIN authentication. This vulnerability affects Firefox < 133.
CVE-2024-11702 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 7.5 HIGH
Copying sensitive information from Private Browsing tabs on Android, such as passwords, may have inadvertently stored data in the cloud-based clipboard history if enabled. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11701 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 4.3 MEDIUM
The incorrect domain may have been displayed in the address bar during an interrupted navigation attempt. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11700 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 8.1 HIGH
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.
