| CVE-2025-62496 | ALTO8.8 | A vulnerability exists in the QuickJS engine's BigInt string parsing logic (js_bigint_from_string) when attempting to create a BigInt from a string with an excessively large number of digits.
The function calculates the necessary number of bits (n_bits) required to store the BigInt using the formula:
$$\text{n\_bits} | 16/10/2025 |
| CVE-2025-62495 | ALTO8.8 | An integer overflow vulnerability exists in the QuickJS regular expression engine (libregexp) due to an inconsistent representation of the bytecode buffer size.
* The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\text{size}\_\text{t}$ (an unsigned type, typically 64-bit) for | 16/10/2025 |
| CVE-2025-62494 | ALTO8.8 | A type confusion vulnerability exists in the handling of the string addition (+) operation within the QuickJS engine.
* The code first checks if the left-hand operand is a string.
* It then attempts to convert the right-hand operand to a primitive value using JS_ToPrimitiveFree. This conversion can trigger a c | 16/10/2025 |
| CVE-2025-62493 | MEDIO6.5 | A vulnerability exists in the QuickJS engine's BigInt string conversion logic (js_bigint_to_string1) due to an incorrect calculation of the required number of digits, which in turn leads to reading memory past the allocated BigInt structure.
* The function determines the number of characters (n_digits) needed for t | 16/10/2025 |
| CVE-2025-62492 | MEDIO6.5 | A vulnerability stemming from floating-point arithmetic precision errors exists in the QuickJS engine's implementation of TypedArray.prototype.indexOf() when a negative fromIndex argument is supplied.
* The fromIndex argument (read as a double variable, $d$) is used to calculate the starting position for the search | 16/10/2025 |
| CVE-2025-62491 | ALTO8.8 | A Use-After-Free (UAF) vulnerability exists in the QuickJS engine's standard library when iterating over the global list of unhandled rejected promises (ts->rejected_promise_list).
* The function js_std_promise_rejection_check attempts to iterate over the rejected_promise_list to report unhandled rejections using a | 16/10/2025 |
| CVE-2025-62490 | ALTO8.8 | In quickjs, in js_print_object, when printing an array, the function first fetches the array length and then loops over it. The issue is, printing a value is not side-effect free. An attacker-defined callback could run during js_print_value, during which the array could get resized and len1 become out of bounds. This r | 16/10/2025 |
| CVE-2025-46688 | ALTO8.4 | quickjs-ng through 0.9.0 has an incorrect size calculation in JS_ReadBigInt for a BigInt, leading to a heap-based buffer overflow. QuickJS before 2025-04-26 is also affected. | 27/04/2025 |
| CVE-2023-48184 | BAJO3.9 | QuickJS before 7414e5f has a quickjs.h JS_FreeValueRT use-after-free because of incorrect garbage collection of async functions with closures. | 23/04/2024 |
| CVE-2023-48183 | ALTO7.5 | QuickJS before c4cdd61 has a build_for_in_iterator NULL pointer dereference because of an erroneous lexical scope of "this" with eval. | 23/04/2024 |
| CVE-2023-31922 | ALTO7.5 | QuickJS commit 2788d71 was discovered to contain a stack-overflow via the component js_proxy_isArray at quickjs.c. | 12/05/2023 |
| CVE-2020-22876 | ALTO7.5 | Buffer Overflow vulnerability in quickjs.c in QuickJS, allows remote attackers to cause denial of service. This issue is resolved in the 2020-07-05 release. | 13/07/2021 |
