|---|---|---|---|---|---|
| CVE-2023-4578 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| When calling `JS::CheckRegExpSyntax` a Syntax Error could have been set which would end in calling `convertToRuntimeErrorAndClear`. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | |||||
| CVE-2023-4577 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| When `UpdateRegExpStatics` attempted to access `initialStringHeap` it could already have been garbage collected prior to entering the function, which could potentially have led to an exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | |||||
| CVE-2023-4576 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2026-06-17 | N/A | 8.6 HIGH |
| On Windows, an integer overflow could occur in `RecordedSourceSurfaceCreation` which resulted in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | |||||
| CVE-2023-4575 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | |||||
| CVE-2023-4574 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | |||||
| CVE-2023-4573 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-06-17 | N/A | 6.5 MEDIUM |
| When receiving rendering data over IPC `mStream` could have been destroyed when initialized, which could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | |||||
| CVE-2023-4421 | 1 Mozilla | 1 Nss | 2026-06-17 | N/A | 6.5 MEDIUM |
| The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. This vulnerability affects NSS < 3.61. | |||||
| CVE-2023-4104 | 1 Mozilla | 1 Vpn | 2026-06-17 | N/A | 5.5 MEDIUM |
| An invalid Polkit Authentication check and missing authentication requirements for D-Bus methods allowed any local user to configure arbitrary VPN setups. *This bug only affects Mozilla VPN on Linux. Other operating systems are unaffected.* This vulnerability affects Mozilla VPN 2.16.1 < (Linux). | |||||
| CVE-2023-4058 | 1 Mozilla | 1 Firefox | 2026-06-17 | N/A | 9.8 CRITICAL |
| Memory safety bugs present in Firefox 115. 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 < 116. | |||||

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 < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. | |||||
| CVE-2023-4056 | 2 Debian, Mozilla | 2 Debian Linux, Firefox | 2026-06-17 | N/A | 9.8 CRITICAL |
| Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. 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.

| CVE-2023-4055 | 2 Debian, Mozilla | 2 Debian Linux, Firefox | 2026-06-17 | N/A | 7.5 HIGH |
| When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the host was no longer consistent with expected cookie jar state. This could have caused requests to be sent with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. | |||||
| CVE-2023-4054 | 2 Microsoft, Mozilla | 2 Windows, Firefox | 2026-06-17 | N/A | 5.5 MEDIUM |

Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 102.14, Firefox ESR < 115.1, Thunderbird < 102.14, and Thunderbird < 115.1. | |||||
| CVE-2023-4053 | 1 Mozilla | 1 Firefox | 2026-06-17 | N/A | 6.5 MEDIUM |
| A website could have obscured the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL.

| CVE-2023-42808 | 1 Mozilla | 1 Common Voice | 2026-06-17 | N/A | 6.1 MEDIUM |
| Common Voice is the web app for Mozilla Common Voice, a platform for collecting speech donations in order to create public domain datasets for training voice recognition-related tools. Version 1.88.2 is vulnerable to reflected Cross-Site Scripting given that user-controlled data flows to a path expression (path of a network request). This issue may lead to reflected Cross-Site Scripting (XSS) in the context of Common Voice’s server origin. As of time of publication, it is unknown whether any patches or workarounds exist. | |||||
