| CVE-2026-56403 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in storeAtts. | ||||
| CVE-2026-56404 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in addBinding. | ||||
| CVE-2026-56405 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in getAttributeId. | ||||
| CVE-2026-56406 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in XML_ParseBuffer because it lacked a check that was present in XML_Parse. | ||||
| CVE-2026-56411 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| xmlwf in libexpat before 2.8.2 has an integer overflow in endDoctypeDecl via NOTATION declarations. | ||||
| CVE-2026-56412 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 4.9 Medium |
| libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219. | ||||
| CVE-2026-56410 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| xmlwf in libexpat before 2.8.2 has an integer overflow in resolveSystemId. | ||||
| CVE-2026-56409 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.5 Medium |
| xmlwf in libexpat before 2.8.2 has an integer overflow for the output filename when -d outputDir is used. | ||||
| CVE-2026-56408 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in copyString. | ||||
| CVE-2026-56407 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| libexpat before 2.8.2 has an integer overflow in doProlog that is related to storeEntityValue and entity textLen. | ||||
| CVE-2026-56132 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 6.9 Medium |
| In libexpat before 2.8.2, there is a heap-based buffer overflow in doProlog in xmlparse.c because scaffold backing array reallocation is mishandled when there is data-structure sharing across parsers. | ||||
| CVE-2026-56131 | 1 Libexpat Project | 1 Libexpat | 2026-06-22 | 4.9 Medium |
| libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_ResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur (similar to the CVE-2026-50219 situation). | ||||
| CVE-2026-50219 | 1 Libexpat Project | 1 Libexpat | 2026-06-04 | 4.9 Medium |
| libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_GetBuffer, XML_Parse, XML_ParseBuffer, XML_ParserFree, or XML_ParserReset from within handlers in cases of a policy violation. Thus, a use-after-free can occur, | ||||
| CVE-2026-25210 | 1 Libexpat Project | 1 Libexpat | 2026-06-02 | 6.9 Medium |
| In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize because there is no integer overflow check for tag buffer reallocation. | ||||
| CVE-2026-24515 | 1 Libexpat Project | 1 Libexpat | 2026-06-02 | 2.9 Low |
| In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data. | ||||
| CVE-2025-66382 | 1 Libexpat Project | 1 Libexpat | 2026-06-02 | 2.9 Low |
| In libexpat through 2.7.3, a crafted file with an approximate size of 2 MiB can lead to dozens of seconds of processing time. | ||||
| CVE-2026-45186 | 1 Libexpat Project | 1 Libexpat | 2026-05-14 | 2.9 Low |
| In libexpat before 2.8.1, the computational complexity of attribute name collision checks allows a denial of service via moderately sized crafted XML input. | ||||
| CVE-2025-59375 | 1 Libexpat Project | 1 Libexpat | 2026-05-12 | 7.5 High |
| libexpat in Expat before 2.7.2 allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing. | ||||
