🚨 Your current dependencies have known security vulnerabilities 🚨
This dependency update fixes known security vulnerabilities. Please see the details below and assess their impact carefully. We recommend to merge and deploy this as soon as possible!
Here is everything you need to know about this update. Please take a good look at what changed and the test results before merging this pull request.
In Nokogiri versions <= 1.11.0.rc3, XML Schemas parsed by Nokogiri::XML::Schema
are trusted by default, allowing external resources to be accessed over the
network, potentially enabling XXE or SSRF attacks.
This behavior is counter to
the security policy followed by Nokogiri maintainers, which is to treat all input
as untrusted by default whenever possible.
Please note that this security
fix was pushed into a new minor version, 1.11.x, rather than a patch release to
the 1.10.x branch, because it is a breaking change for some schemas and the risk
was assessed to be "Low Severity".
Affected Versions
Nokogiri <= 1.10.10 as well as prereleases 1.11.0.rc1, 1.11.0.rc2, and 1.11.0.rc3
Mitigation
There are no known workarounds for affected versions. Upgrade to Nokogiri 1.11.0.rc4 or later.
If, after upgrading to 1.11.0.rc4 or later, you wish
to re-enable network access for resolution of external resources (i.e., return to
the previous behavior):
Ensure the input is trusted. Do not enable this option
for untrusted input.
When invoking the Nokogiri::XML::Schema constructor,
pass as the second parameter an instance of Nokogiri::XML::ParseOptions with the NONET flag turned off.
So if your previous code was:
# in v1.11.0.rc3 and earlier, this call allows resources to be accessed over the network# but in v1.11.0.rc4 and later, this call will disallow network access for external resourcesschema=Nokogiri::XML::Schema.new(schema)# in v1.11.0.rc4 and later, the following is equivalent to the code above# (the second parameter is optional, and this demonstrates its default value)schema=Nokogiri::XML::Schema.new(schema,Nokogiri::XML::ParseOptions::DEFAULT_SCHEMA)
Then you can add the second parameter to indicate that the input is trusted by changing it to:
# in v1.11.0.rc3 and earlier, this would raise an ArgumentError# but in v1.11.0.rc4 and later, this allows resources to be accessed over the networkschema=Nokogiri::XML::Schema.new(trusted_schema,Nokogiri::XML::ParseOptions.new.nononet)
Faster, more reliable installation: Native Gems for Linux and OSX/Darwin
"Native gems" contain pre-compiled libraries for a specific machine architecture. On supported platforms, this removes the need for compiling the C extension and the packaged libraries. This results in much faster installation and more reliable installation, which as you probably know are the biggest headaches for Nokogiri users.
We've been shipping native Windows gems since 2009, but starting in v1.11.0 we are also shipping native gems for these platforms:
Linux: x86-linux and x86_64-linux -- including musl platforms like alpine
OSX/Darwin: x86_64-darwin and arm64-darwin
We'd appreciate your thoughts and feedback on this work at #2075.
Dependencies
Ruby
This release introduces support for Ruby 2.7 and 3.0 in the precompiled native gems.
JRuby 9.1, which is the Ruby 2.3-compatible release.
Gems
Explicitly add racc as a runtime dependency. [#1988] (Thanks, @voxik!)
[MRI] Upgrade mini_portile2 dependency from ~> 2.4.0 to ~> 2.5.0 [#2005] (Thanks, @alejandroperea!)
Security
See note below about CVE-2020-26247 in the "Changed" subsection entitled "XML::Schema parsing treats input as untrusted by default".
Added
Add Node methods for manipulating "keyword attributes" (for example, class and rel): #kwattr_values, #kwattr_add, #kwattr_append, and #kwattr_remove. [#2000]
Add support for CSS queries a:has(> b), a:has(~ b), and a:has(+ b). [#688] (Thanks, @jonathanhefner!)
Add Node#value? to better match expected semantics of a Hash-like object. [#1838, #1840] (Thanks, @MatzFan!)
[CRuby] Add Nokogiri::XML::Node#line= for use by downstream libs like nokogumbo. [#1918] (Thanks, @stevecheckoway!)
nokogiri.gemspec is back after a 10-year hiatus. We still prefer you use the official releases, but master is pretty stable these days, and YOLO.
Performance
[CRuby] The CSS ~= operator and class selector . are about 2x faster. [#2137, #2135]
[CRuby] Patch libxml2 to call strlen from xmlStrlen rather than the naive implementation, because strlen is generally optimized for the architecture. [#2144] (Thanks, @ilyazub!)
Improve performance of some namespace operations. [#1916] (Thanks, @ashmaroli!)
Avoid creation of unnecessary zero-length String objects. [#1970] (Thanks, @ashmaroli!)
Always compile libxml2 and libxslt with '-O2' [#2022, #2100] (Thanks, @ilyazub!)
[JRuby] Lots of code cleanup and performance improvements. [#1934] (Thanks, @kares!)
[CRuby] RelaxNG.from_document no longer leaks memory. [#2114]
Improved
[CRuby] Handle incorrectly-closed HTML comments as WHATWG recommends for browsers. [#2058] (Thanks to HackerOne user mayflower for reporting this!)
{HTML,XML}::Document#parse now accept Pathname objects. Previously this worked only if the referenced file was less than 4096 bytes long; longer files resulted in undefined behavior because the read method would be repeatedly invoked. [#1821, #2110] (Thanks, @doriantaylor and @phokz!)
[CRuby] Nokogumbo builds faster because it can now use header files provided by Nokogiri. [#1788] (Thanks, @stevecheckoway!)
Add frozen_string_literal: true magic comment to all lib files. [#1745] (Thanks, @oniofchaos!)
[JRuby] Clean up deprecated calls into JRuby. [#2027] (Thanks, @headius!)
Fixed
HTML Parsing in "strict" mode (i.e., the RECOVER parse option not set) now correctly raises a XML::SyntaxError exception. Previously the value of the RECOVER bit was being ignored by CRuby and was misinterpreted by JRuby. [#2130]
The CSS ~= operator now correctly handles non-space whitespace in the class attribute. commit e45dedd
The switch to turn off the CSS-to-XPath cache is now thread-local, rather than being shared mutable state. [#1935]
The Node methods add_previous_sibling, previous=, before, add_next_sibling, next=, after, replace, and swap now correctly use their parent as the context node for parsing markup. These methods now also raise a RuntimeError if they are called on a node with no parent. [nokogumbo#160]
[JRuby] XML::Schema XSD validation errors are captured in XML::Schema#errors. These errors were previously ignored.
[JRuby] Standardize reading from IO like objects, including StringIO. [#1888, #1897]
[JRuby] Fix how custom XPath function namespaces are inferred to be less naive. [#1890, #2148]
[JRuby] Clarify exception message when custom XPath functions can't be resolved.
[JRuby] Comparison of Node to Document with Node#<=> now matches CRuby/libxml2 behavior.
[CRuby] Syntax errors are now correctly captured in Document#errors for short HTML documents. Previously the SAX parser used for encoding detection was clobbering libxml2's global error handler.
[CRuby] Fixed installation on AIX with respect to vasprintf. [#1908]
[CRuby] On some platforms, avoid symbol name collision with glibc's canonicalize. [#2105]
[Windows Visual C++] Fixed compiler warnings and errors. [#2061, #2068]
[CRuby] Fixed Nokogumbo integration which broke in the v1.11.0 release candidates. [#1788] (Thanks, @stevecheckoway!)
In Nokogiri versions <= 1.11.0.rc3, XML Schemas parsed by Nokogiri::XML::Schema were trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks.
This behavior is counter to the security policy intended by Nokogiri maintainers, which is to treat all input as untrusted by default whenever possible.
Please note that this security fix was pushed into a new minor version, 1.11.x, rather than a patch release to the 1.10.x branch, because it is a breaking change for some schemas and the risk was assessed to be "Low Severity".
More information and instructions for enabling "trusted input" behavior in v1.11.0.rc4 and later is available at the public advisory.
HTML parser now obeys the strict or norecover parsing option
(Also noted above in the "Fixed" section) HTML Parsing in "strict" mode (i.e., the RECOVER parse option not set) now correctly raises a XML::SyntaxError exception. Previously the value of the RECOVER bit was being ignored by CRuby and was misinterpreted by JRuby.
If you're using the default parser options, you will be unaffected by this fix. If you're passing strict or norecover to your HTML parser call, you may be surprised to see that the parser now fails to recover and raises a XML::SyntaxError exception. Given the number of HTML documents on the internet that libxml2 would consider to be ill-formed, this is probably not what you want, and you can omit setting that parse option to restore the behavior that you have been relying upon.
Apologies to anyone inconvenienced by this breaking bugfix being present in a minor release, but I felt it was appropriate to introduce this fix because it's straightforward to fix any code that has been relying on this buggy behavior.
VersionInfo, the output of nokogiri -v, and related constants
This release changes the metadata provided in Nokogiri::VersionInfo which also affects the output of nokogiri -v. Some related constants have also been changed. If you're using VersionInfo programmatically, or relying on constants related to underlying library versions, please read the detailed changes for Nokogiri::VersionInfo at #2139 and accept our apologies for the inconvenience.
