How severe is CVE-2013-1801?

No CVSS score has been assigned to CVE-2013-1801 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2013-1801?

CVE-2013-1801 affects the following packages: httparty (RubyGems). Ecosystems affected: RubyGems.

How do I fix CVE-2013-1801?

Update httparty to 0.10.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-1801 is resolved across your whole dependency graph.

How do I detect CVE-2013-1801 in my RubyGems dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for httparty, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2013-1801 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is CVE-2013-1801 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2013-1801, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2013-1801?

CVE-2013-1801 has an EPSS (Exploit Prediction Scoring System) score of 4.4%, placing it in the 91th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2013-1801?

CVE-2013-1801 is classified as CWE-264 (CWE-264). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2013-1801 published, and has it been updated?

CVE-2013-1801 was published on October 24, 2017 and was last updated on November 29, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

💎httparty

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.

Description

The httparty gem 0.9.0 and earlier for Ruby does not properly restrict casts of string values, which might allow remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) by leveraging Action Pack support for YAML type conversion, a similar vulnerability to CVE-2013-0156.
