The website field was HTML-escaped using quote=False, which left single and double quotes unescaped. Since the frontend inserts the website value directly into a single-quoted href attribute via string concatenation, a single quote in the URL breaks out of the attribute context, allowing injection of arbitrary event handlers (e.g. onmouseover, onclick).\n\nThe same escaping was missing entirely from the user-facing comment edit endpoint (PUT /id/<id>) and the moderation edit endpoint (POST /id/<id>/edit/<key>).\n\nAny visitor to a page embedding isso comments is impacted. No authentication or interaction beyond mouse movement is required to trigger a payload — an attacker can post a comment anonymously (moderation is off by default) with a crafted website URL, and the payload persists in the database and fires on every page load. With the full-page invisible overlay technique described in the report, the victim only needs to move their mouse.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2026-27469", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00108", "scoring_system": "epss", "scoring_elements": "0.28558", "published_at": "2026-06-09T12:55:00Z" }, { "value": "0.00108", "scoring_system": "epss", "scoring_elements": "0.28552", "published_at": "2026-06-08T12:55:00Z" }, { "value": "0.00108", "scoring_system": "epss", "scoring_elements": "0.28586", "published_at": "2026-06-07T12:55:00Z" }, { "value": "0.00108", "scoring_system": "epss", "scoring_elements": "0.28663", "published_at": "2026-06-05T12:55:00Z" }, { "value": "0.00108", "scoring_system": "epss", "scoring_elements": "0.28623", "published_at": "2026-06-06T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2026-27469" }, { "reference_url": "https://docs.python.org/3/library/html.html#html.escape", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.1", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-02-24T18:49:50Z/" } ], "url": "https://docs.python.org/3/library/html.html#html.escape" }, { "reference_url": "https://github.com/isso-comments/isso", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.1", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/isso-comments/isso" }, { "reference_url": "https://github.com/isso-comments/isso/commit/0afbfe0691ee237963e8fb0b2ee01c9e55ca2144", "reference_id": "", "reference_type": "", "scores": [ { "value": "6.1", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-02-24T18:49:50Z/" } ], "url": "https://github.com/isso-comments/isso/commit/0afbfe0691ee237963e8fb0b2ee01c9e55ca2144" }, { "reference_url": "https://nvd.nist.gov/vuln/detail/CVE-2026-27469", "reference_id": "CVE-2026-27469", "reference_type": "", "scores": [ { "value": "6.1", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-27469" }, { "reference_url": "https://github.com/advisories/GHSA-9fww-8cpr-q66r", "reference_id": "GHSA-9fww-8cpr-q66r", "reference_type": "", "scores": [ { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-9fww-8cpr-q66r" }, { "reference_url": "https://github.com/isso-comments/isso/security/advisories/GHSA-9fww-8cpr-q66r", "reference_id": "GHSA-9fww-8cpr-q66r", "reference_type": "", "scores": [ { "value": "6.1", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N" }, { "value": "MODERATE", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "MODERATE", "scoring_system": "generic_textual", "scoring_elements": "" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-02-24T18:49:50Z/" } ], "url": "https://github.com/isso-comments/isso/security/advisories/GHSA-9fww-8cpr-q66r" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/74239?format=api", "purl": "pkg:pypi/isso@0.13.2", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/isso@0.13.2" } ], "aliases": [ "CVE-2026-27469", "GHSA-9fww-8cpr-q66r" ], "risk_score": 3.1, "exploitability": "0.5", "weighted_severity": "6.2", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-p5pe-hean-kfbf" } ], "fixing_vulnerabilities": [], "risk_score": "3.1", "resource_url": "http://public2.vulnerablecode.io/packages/pkg:pypi/isso@0.12.6.1" }
