CVE-2023-48699 has a CVSS score of 8.4/10, rated HIGH. Immediate patching is strongly recommended.

Which products are affected by CVE-2023-48699?

Affected package information for CVE-2023-48699 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2023-48699?

Apply the ubertidavide fastbots security patch or hotfix for CVE-2023-48699 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2023-48699 across my infrastructure?

Inventory every ubertidavide fastbots deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2023-48699 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2023-48699?

O3 detects and blocks CVE-2023-48699 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2023-48699 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-48699, 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-2023-48699?

CVE-2023-48699 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 50th 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-2023-48699?

CVE-2023-48699 is classified as CWE-95 (CWE-95), Code Injection (CWE-94). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2023-48699?

CVE-2023-48699 affects ubertidavide fastbots. Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2023-48699 published, and has it been updated?

CVE-2023-48699 was published on November 21, 2023 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

fastbots is a library for fast bot and scraper development using selenium and the Page Object Model (POM) design. Prior to version 0.1.5, an attacker could modify the locators.ini locator file with python code that without proper validation it's executed and it could lead to rce. The vulnerability is in the function def __locator__(self, locator_name: str) in page.py. In order to mitigate this issue, upgrade to fastbots version 0.1.5 or above.
