There is a possible regular expression based DoS vulnerability in Active Support. This vulnerability has been assigned the CVE identifier CVE-2023-22796. Versions Affected: All Not affected: None Fixed Versions: 6.1.7.1, 7.0.4.1 Impact A specially crafted string passed to the underscore method can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability. This affects String#underscore, ActiveSupport::Inflector.underscore, String#titleize, and any other methods using these. All users running an affected release should either upgrade or use one of the workarounds immediately. Releases The FIXED releases are available at the normal locations. Workarounds There are no feasible workarounds for this issue. Users on Ruby 3.2.0 or greater may be able to reduce the impact by configuring Regexp.timeout. Patches To aid users who aren’t able to upgrade immedi...

There is a vulnerability in Action Controller’s redirect_to. This vulnerability has been assigned the CVE identifier CVE-2023-22797. Versions Affected: >= 7.0.0 Not affected: < 7.0.0 Fixed Versions: 7.0.4.1 Impact There is a possible open redirect when using the redirect_to helper with untrusted user input. Vulnerable code will look like this: ``` redirect_to(params[:some_param]) ``` Rails 7.0 introduced protection against open redirects from calling redirect_to with untrusted user input. In prior versions the developer was fully responsible for only providing trusted input. However the check introduced could be bypassed by a carefully crafted URL. All users running an affected release should either upgrade or use one of the workarounds immediately. Releases The FIXED releases are available at the normal locations. Workarounds There are no feasible workarounds for this issue. Patches To aid users who aren’t able to upgrade immediately we have provided patches for the two suppor...

There is a potential denial of service vulnerability present in ActiveRecord’s PostgreSQL adapter. This has been assigned the CVE identifier CVE-2022-44566. Versions Affected: All. Not affected: None. Fixed Versions: 7.0.4.1, 6.1.7.1 Impact In ActiveRecord <7.0.4.1 and <6.1.7.1, when a value outside the range for a 64bit signed integer is provided to the PostgreSQL connection adapter, it will treat the target column type as numeric. Comparing integer values against numeric values can result in a slow sequential scan resulting in potential Denial of Service. Releases The fixed releases are available at the normal locations. Workarounds Ensure that user supplied input which is provided to ActiveRecord clauses do not contain integers wider than a signed 64bit representation or floats. Patches To aid users who aren’t able to upgrade immediately we have provided patches for the supported release series in accordance with our maintenance policy 1 regarding security issues. They are in ...

There is a possible regular expression based DoS vulnerability in Action Dispatch related to the If-None-Match header. This vulnerability has been assigned the CVE identifier CVE-2023-22795. Versions Affected: All Not affected: None Fixed Versions: 6.1.7.1, 7.0.4.1 Impact A specially crafted HTTP If-None-Match header can cause the regular expression engine to enter a state of catastrophic backtracking, when on a version of Ruby below 3.2.0. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately. Releases The FIXED releases are available at the normal locations. Workarounds We recommend that all users upgrade to one of the FIXED versions. In the meantime, users can mitigate this vulnerability by using a load balancer or other device to filter out malicious If-None-Match headers before they reach the application. Users on Ruby 3.2....

There is a possible vulnerability in ActiveRecord related to the sanitization of comments. This vulnerability has been assigned the CVE identifier CVE-2023-22794. Versions Affected: >= 6.0.0 Not affected: < 6.0.0 Fixed Versions: 6.0.6.1, 6.1.7.1, 7.0.4.1 Impact Previously the implementation of escaping for comments was insufficient for If malicious user input is passed to either the annotate query method, the optimizer_hints query method, or through the QueryLogs interface which automatically adds annotations, it may be sent to the database with insufficient sanitization and be able to inject SQL outside of the comment. In most cases these interfaces won’t be used with user input and users should avoid doing so. Example vulnerable code: ``` Post.where(id: 1).annotate("#{params[:user_input]}") Post.where(id: 1).optimizer_hints("#{params[:user_input]}") ``` Example vulnerable QueryLogs configuration (the default configuration is not vulnerable): ``` config.active_record.query_log_t...

There is a possible denial of service vulnerability in the Range header parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2022-44570. Versions Affected: >= 1.5.0 Not affected: None. Fixed Versions: 2.0.9.2, 2.1.4.2, 2.2.6.2, 3.0.0.1 Impact Carefully crafted input can cause the Range header parsing component in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector.

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the `Cookie.parse` function and other aspects of the API, which use an insecure regular expression for parsing cookie values. Applications could be stalled for extended periods of time if untrusted input is passed to cookie values or attempted to parse from request headers. Proof of concept: ``` ts\nconst { CookieJar } = require("cookiejar"); const jar = new CookieJar(); const start = performance.now(); const attack = "a" + "t".repeat(50_000); jar.setCookie(attack); console.log(`CookieJar.setCookie(): ${performance.now() - start}ms`); ``` ``` CookieJar.setCookie(): 2963.214399999939ms ```
