    Title
    Nokogiri before 1.19.1 Unchecked Return Value canonicalize
    Summary
    Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

    Title
    Nokogiri before 1.19.3 Memory Leak via XSLT Transform
    Summary
    Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.

    Title
    Nokogiri before 1.19.3 ReDoS via CSS selector tokenizer
    Summary
    Nokogiri versions before 1.19.3 contain regular expression denial of service vulnerabilities in the CSS selector tokenizer affecting string-literal and identifier tokenization. Attackers can inject adversarial CSS selectors into methods like Node#css, Node#at_css, and Searchable#search to cause exponential regex backtracking and denial of service.

    Title
    Nokogiri before 1.19.4 Invalid Memory Read via initialize_copy_with_args
    Summary
    Nokogiri versions before 1.19.4 contain a possible invalid (out-of-bounds) memory read in the protected internal Node#initialize_copy_with_args helper behind Node#dup and #clone, which unwrapped its source argument as an xmlNode without a type check. If application code calls this protected method with a non-Node argument (e.g., a Namespace), it reads an xmlNs out of bounds, crashing the process. This is only triggerable by a programming error and cannot be triggered by untrusted input or normal use of the public API. Only CRuby is affected. Version 1.19.4 adds a type check and raises TypeError.

    Title
    Nokogiri before 1.14.3 Null Pointer Dereference via libxml2
    Summary
    Nokogiri before 1.14.3 (CRuby implementation only, when using the packaged libxml2) bundles libxml2 v2.10.3, which is vulnerable to NULL pointer dereferences in XML Schema processing (xmlSchemaFixupComplexType, CVE-2023-28484, and xmlSchemaCheckCOSSTDerivedOK). An attacker who supplies a crafted/malformed XML schema can cause libxml2 to dereference a NULL pointer and potentially segfault, resulting in a denial of service. Nokogiri 1.14.3 upgrades the packaged libxml2 to v2.10.4 to resolve these issues.

    Title
    Nokogiri before 1.13.2 Multiple Vulnerabilities via libxml2 libxslt
    Summary
    Nokogiri before 1.13.2 (CRuby, when using packaged libraries) ships vendored libxml2 2.9.12 and libxslt 1.1.34, which are affected by two upstream CVEs. Via CVE-2021-30560 in libxslt, an application transforming XML with untrusted XSL stylesheets is vulnerable to a denial-of-service attack. Via CVE-2022-23308 in libxml2, an application parsing an untrusted document with parse option DTDVALID set to true and NOENT set to false may be vulnerable to denial of service, memory disclosure, or code execution. Nokogiri 1.13.2 upgrades vendored libxml2 to 2.9.13 and libxslt to 1.1.35.

    Title
    Nokogiri before 1.13.5 Integer Overflow via libxml2
    Summary
    Nokogiri versions before 1.13.5 contain an integer overflow vulnerability in packaged libxml2 buffer handling functions that allows attackers to cause out-of-bounds memory writes. Attackers can exploit this by crafting multi-gigabyte XML files to trigger buffer overflows resulting in information disclosure, data modification, or denial of service.

    Title
    Nokogiri before 1.13.9 Multiple Vulnerabilities via libxml2
    Summary
    Nokogiri before 1.13.9 (CRuby implementation using packaged libraries) bundles libxml2 v2.9.14, which is affected by CVE-2022-40304 (data corruption / double-free from an entity reference cycle when entity content is allocated from a dict) and CVE-2022-40303 (integer overflows when parsing with XML_PARSE_HUGE). Nokogiri 1.13.9 upgrades the packaged libxml2 to v2.10.3 to address these issues. Processing crafted XML input may lead to denial of service or memory corruption. (The advisory also references CVE-2022-2309, a NULL pointer dereference via iterwalk/canonicalize, which maintainers determined does not affect Nokogiri users.)

    Title
    Nokogiri before 1.11.4 Multiple Vulnerabilities via libxml2
    Summary
    Nokogiri before 1.11.4 (CRuby implementation only, when the packaged/vendored libxml2 is used) bundles libxml2 2.9.10, which is affected by multiple vulnerabilities addressed in libxml2 2.9.12, including a memory leak in xmlSchemaValidateStream (CVE-2019-20388), a global buffer over-read in xmlEncodeEntitiesInternal (CVE-2020-24977), a heap-based buffer overflow (CVE-2021-3517), and an out-of-bounds read (CVE-2021-3518). Processing crafted XML documents may lead to denial of service, information disclosure, or memory corruption.

    Title
    Nokogiri before 1.19.1 Unchecked Return Value canonicalize
    Summary
    Nokogiri versions before 1.19.1 fail to check the return value from xmlC14NExecute in the canonicalize method, returning an empty string on failure instead of raising an exception. Attackers can exploit this to bypass signature validation in downstream SAML libraries by providing invalid canonicalized XML that is incorrectly accepted as valid.

    Title
    Nokogiri before 1.19.3 Memory Leak via XSLT Transform
    Summary
    Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.

    Title
    Nokogiri before 1.19.3 ReDoS via CSS selector tokenizer
    Summary
    Nokogiri versions before 1.19.3 contain regular expression denial of service vulnerabilities in the CSS selector tokenizer affecting string-literal and identifier tokenization. Attackers can inject adversarial CSS selectors into methods like Node#css, Node#at_css, and Searchable#search to cause exponential regex backtracking and denial of service.

    Title
    Nokogiri before 1.19.4 Invalid Memory Read via initialize_copy_with_args
    Summary
    Nokogiri versions before 1.19.4 contain a possible invalid (out-of-bounds) memory read in the protected internal Node#initialize_copy_with_args helper behind Node#dup and #clone, which unwrapped its source argument as an xmlNode without a type check. If application code calls this protected method with a non-Node argument (e.g., a Namespace), it reads an xmlNs out of bounds, crashing the process. This is only triggerable by a programming error and cannot be triggered by untrusted input or normal use of the public API. Only CRuby is affected. Version 1.19.4 adds a type check and raises TypeError.

    Title
    Nokogiri before 1.14.3 Null Pointer Dereference via libxml2
    Summary
    Nokogiri before 1.14.3 (CRuby implementation only, when using the packaged libxml2) bundles libxml2 v2.10.3, which is vulnerable to NULL pointer dereferences in XML Schema processing (xmlSchemaFixupComplexType, CVE-2023-28484, and xmlSchemaCheckCOSSTDerivedOK). An attacker who supplies a crafted/malformed XML schema can cause libxml2 to dereference a NULL pointer and potentially segfault, resulting in a denial of service. Nokogiri 1.14.3 upgrades the packaged libxml2 to v2.10.4 to resolve these issues.

    Title
    Nokogiri before 1.13.2 Multiple Vulnerabilities via libxml2 libxslt
    Summary
    Nokogiri before 1.13.2 (CRuby, when using packaged libraries) ships vendored libxml2 2.9.12 and libxslt 1.1.34, which are affected by two upstream CVEs. Via CVE-2021-30560 in libxslt, an application transforming XML with untrusted XSL stylesheets is vulnerable to a denial-of-service attack. Via CVE-2022-23308 in libxml2, an application parsing an untrusted document with parse option DTDVALID set to true and NOENT set to false may be vulnerable to denial of service, memory disclosure, or code execution. Nokogiri 1.13.2 upgrades vendored libxml2 to 2.9.13 and libxslt to 1.1.35.

    Title
    Nokogiri before 1.13.5 Integer Overflow via libxml2
    Summary
    Nokogiri versions before 1.13.5 contain an integer overflow vulnerability in packaged libxml2 buffer handling functions that allows attackers to cause out-of-bounds memory writes. Attackers can exploit this by crafting multi-gigabyte XML files to trigger buffer overflows resulting in information disclosure, data modification, or denial of service.

    Title
    Nokogiri before 1.13.9 Multiple Vulnerabilities via libxml2
    Summary
    Nokogiri before 1.13.9 (CRuby implementation using packaged libraries) bundles libxml2 v2.9.14, which is affected by CVE-2022-40304 (data corruption / double-free from an entity reference cycle when entity content is allocated from a dict) and CVE-2022-40303 (integer overflows when parsing with XML_PARSE_HUGE). Nokogiri 1.13.9 upgrades the packaged libxml2 to v2.10.3 to address these issues. Processing crafted XML input may lead to denial of service or memory corruption. (The advisory also references CVE-2022-2309, a NULL pointer dereference via iterwalk/canonicalize, which maintainers determined does not affect Nokogiri users.)

    Title
    Nokogiri before 1.11.4 Multiple Vulnerabilities via libxml2
    Summary
    Nokogiri before 1.11.4 (CRuby implementation only, when the packaged/vendored libxml2 is used) bundles libxml2 2.9.10, which is affected by multiple vulnerabilities addressed in libxml2 2.9.12, including a memory leak in xmlSchemaValidateStream (CVE-2019-20388), a global buffer over-read in xmlEncodeEntitiesInternal (CVE-2020-24977), a heap-based buffer overflow (CVE-2021-3517), and an out-of-bounds read (CVE-2021-3518). Processing crafted XML documents may lead to denial of service, information disclosure, or memory corruption.
