|---|---|---|---|---|---|---|
| CVE-2025-58050 | The PCRE2 library is a set of C functions that implement regular expression pattern matching. In version 10.45, a heap-buffer-overflow read vulnerability exists in the PCRE2 regular expression matching engine, specifically within the handling of the (*scs:...) (Scan SubString) verb when combined with (*ACCEPT) in src/pcre2_match.c. This vulnerability may potentially lead to information disclosure if the out-of-bounds data read during the memcmp affects the final match result in a way observable | [email protected] | 6.9 | 0.05% | 2025-08-27 | 2025-09-09 |
| CVE-2022-41409 | Integer overflow vulnerability in pcre2test before 10.41 allows attackers to cause a denial of service or other unspecified impacts via negative input. | [email protected] | 7.5 | 0.05% | 2023-07-18 | 2024-11-21 |
| CVE-2022-1587 | An out-of-bounds read vulnerability was discovered in the PCRE2 library in the get_recurse_data_length() function of the pcre2_jit_compile.c file. This issue affects recursions in JIT-compiled regular expressions caused by duplicate data transfers. | [email protected] | 9.1 | 0.25% | 2022-05-16 | 2024-11-21 |

This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT. | [email protected] | 9.1 | 0.58% | 2022-05-16 | 2025-03-25 |

| CVE-2019-20838 | libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R has more than one fixed quantifier, a related issue to CVE-2019-20454. | [email protected] | 7.5 | 0.23% | 2020-06-15 | 2024-11-21 |
| CVE-2019-20454 | An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c. | [email protected] | 7.5 | 0.09% | 2020-02-14 | 2024-11-21 |
| CVE-2015-2326 | The pcre_compile2 function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code and cause a denial of service (out-of-bounds read) via regular expression with a group containing both a forward referencing subroutine call and a recursive back reference, as demonstrated by "((?+1)(\1))/". | [email protected] | 5.5 | 0.59% | 2020-01-14 | 2024-11-21 |
| CVE-2015-2325 | The compile_branch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier. | [email protected] | 7.8 | 0.47% | 2020-01-14 | 2024-11-21 |
| CVE-2017-16231 | In PCRE 8.41, after compiling, a pcretest load test PoC produces a crash overflow in the function match() in pcre_exec.c because of a self-recursive call. NOTE: third parties dispute the relevance of this report, noting that there are options that can be used to limit the amount of stack that is used | [email protected] | 5.5 | 0.07% | 2019-03-21 | 2024-11-21 |
| CVE-2017-11164 | In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion (uncontrolled recursion) when processing a crafted regular expression. | [email protected] | 7.5 | 0.11% | 2017-07-11 | 2026-05-13 |
