Vulnerability Details
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. "1e10000"), which "BigDecimal" expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Vulnerability Details
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. "NumberToDelimitedConverter" uses a lookahead-based regular expression with "gsub!" to insert thousands delimiters. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, the interaction between the repeated lookahead group and "gsub!" can produce quadratic time complexity on long digit strings. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Vulnerability Details
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, "SafeBuffer#%" does not propagate the "@html_unsafe" flag to the newly created buffer. If a "SafeBuffer" is mutated in place (e.g. via "gsub!") and then formatted with "%" using untrusted arguments, the result incorrectly reports "html_safe? == true", bypassing ERB auto-escaping and possibly leading to XSS. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
