CVE-2020-7740
HIGHCVE-2020-7740 is a high-severity (CVSS 8.2) Improper Input Validation vulnerability in node-pdf-generator. O3 Security confirms whether CVE-2020-7740 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Server-Side Request Forgery in node-pdf-generator
Real-World Exposure
node-pdf-generatorReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
This affects all versions of package node-pdf-generator up to and including 0.0.6. Due to lack of user input validation and sanitization done to the content given to node-pdf-generator, it is possible for an attacker to craft a url that will be passed to an external server allowing an SSRF attack.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-pdf-generator. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of node-pdf-generator has shipped for CVE-2020-7740 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2020-7740 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2020-7740. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
