Capabilities

Built for the threats that haven't happened yet.

001

Threat Cartography

Continuous mapping of your attack surface across every layer — from exposed APIs to shadow infrastructure nobody told you about.

002

Risk Prioritisation

Correlates scan findings with CVE intelligence and severity data so teams can focus on the exposures most likely to matter.

003

Automated Validation

Runs repeatable security checks and rescans to help confirm findings and verify whether remediation changed the exposed attack surface.

004

Protocol & Configuration Checks

Reviews exposed services, TLS configuration, DNS, headers, and detected technologies for common weaknesses and outdated components.

005

Adversary Emulation

Continuous red-team operations powered by threat actor profiles. We think like them so you don't have to.

006

Sentinel Protocol

Distributed sensor mesh across your infrastructure. Silent watchers that leap into action the moment anomalies surface.

Real-Time Intelligence

The network never sleeps.

Our Approach

Defence in depth,
by design.

01

Map

Comprehensive reconnaissance of your digital terrain. We discover assets, dependencies, and exposures across cloud, on-prem, and hybrid environments.

02

Analyse

Contextual risk scoring powered by threat intelligence feeds, adversary TTPs, and your unique business logic. Not just CVEs — real-world exploitability.

03

Fortify

Automated hardening recommendations deployed through your existing CI/CD pipeline. Security becomes part of the build, not an afterthought.

04

Evolve

Continuous learning from global threat landscapes. The platform adapts its defensive posture as adversary capabilities shift and new vectors emerge.

OverviewGetting StartedAuthenticationAPI ReferenceIntegrations

Overview

Vesamuni is an early-stage cyber security platform that brings vulnerability scanning, CVE intelligence, attack surface discovery, and security reporting into a single dashboard.

Account access uses server-side sessions, Argon2 password hashing, CSRF protection, secure cookies, and optional authenticator-based two-factor authentication.

Getting Started

Vesamuni is currently in early access. Approved clients receive an account from the team.

Step 1
Receive and accept your client invitation.

Step 2
Sign in and add the public URL you want to monitor.

Step 3
Enable two-factor authentication from the security dashboard.

Step 4
Contact the team to confirm scan scope during early access.

Authentication

The current client dashboard uses secure server-side sessions. Public API credentials are not generally available during early access.

API Reference

A public scanning API is planned but not yet released. Current HTTP endpoints support the website, account management, billing, and internal administration.

Integrations

Stripe billing is available now. Additional workflow integrations and public SDKs are roadmap items and will be documented only when released.

About

We build what defenders need.

Vesamuni was founded with a singular conviction: the asymmetry between attackers and defenders is a design problem, not an inevitability.

Our Philosophy

We don't believe in security theatre. Every feature should help teams discover, understand, or remediate a real exposure. Vesamuni is being built iteratively with feedback from security-minded operators and developers.

Global Presence

We operate from Melbourne, Australia and Colombo, Sri Lanka. Our distributed startup team combines product development with security research across the APAC region.

Why Two Continents?

Melbourne connects us to Australia's security market. Colombo connects us to South Asia's rapidly growing tech ecosystem. The two locations give the team access to different customers, talent pools, and perspectives.

The Name

Vesamuni (වෙසමුනි) — In Sri Lankan folklore, Vesamuni is the fearsome king of demons. He rules the Yakkas with an iron fist, commanding spirits that once spread chaos across the land. Yet he chose to protect rather than destroy — forbidding his demons from killing, transforming them into instruments of order.

Armed with a magical golden sword that flies from his hand to strike down enemies before they see it coming, Vesamuni embodies power turned to protection.

We do the same. The tools of attackers, wielded by defenders.

CVE-2026-54897: Oj (Optimized JSON) is a JSON parser and Object marsha

By Vesamuni Research / Updated 02/07/2026
CVE-2026-54897: Oj (Optimized JSON) is a JSON parser and Object marsha

CVE-2026-54897 analysis covering impact, affected products, versions, remediation, and cross-checked defender guidance.

CVE-2026-54897 is a vulnerability published by NVD on 7/1/2026.

What happened

Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to 3.17.2, Oj::Doc iterators (each_value, each_child, each_leaf) were vulnerable to a heap use-after-free. When a Ruby block yielded during iteration calls doc.close or d.close, the document's heap memory is freed while the C iterator is still running. When control returns from the block, the iterator reads from the freed region, producing a use-after-free accessible from pure Ruby. This issue has been fixed in version 3.17.2.

Affected products and versions

  • NVD has not published a normalized affected-product configuration yet.

Severity and weakness

CVSS: LOW 2.1. Vector: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X.

Weaknesses: CWE-416.

Known exploitation

No CISA KEV entry is currently attached to the NVD record.

What defenders should do

  1. Identify whether the affected product and version range exists in production.
  2. Review vendor advisories and release notes before change windows.
  3. Patch, upgrade, disable the vulnerable component, or apply vendor mitigations.
  4. Verify the running version after deployment, not only the package inventory.

Official and supporting references

  • No vendor advisory tagged by NVD at draft time.
