HIGHNVD 6.57.4
EchelonGraph scoreHIGH confidence

“▲” beside the score: it is higher than NVD's CVSS score.

Score elevated to 7.4 because EPSS predicted 50% probability of exploitation within the next 30 days (98th percentile of EPSS-scored CVEs) when EchelonGraph scored this CVE. NVD baseline CVSS 6.5 retained for reference. Confidence: see factors.

Triggered by: EPSS exploit prediction (continuous uplift above 30%)

Fixed versions, as the CVE record's CNA (PHP Group) states them: "Upgrade to PHP 7.4.31, 8.0.24, or 8.1.11."

In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a __Host- or __Secure- cookie by PHP applications.

EG Risk 49/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Data Freshness Timeline

(refreshed 9× in last 7d / 37× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 96 of 188 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 4 repeat rows among the latest 100 are merged into the row they repeat. The 92 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2022-31629?
CVE-2022-31629 is a high-severity vulnerability; its CVE record was published on September 28, 2022. In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a __Host- or __Secure- cookie by PHP applications.
When was CVE-2022-31629 made public?
CVE-2022-31629 was made public on September 27, 2022: that is the date its CVE record's CNA, PHP Group, gives for when the vulnerability was made public. The CVE record itself was published on September 28, 2022. EchelonGraph's copy of the record carries a last-modified date of November 4, 2025; the record at its source may have been updated since.
Is CVE-2022-31629 actively exploited?
CVE-2022-31629 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 50% probability of exploitation in the next 30 days (98th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2022-31629?
CVE-2022-31629 has a CVSS v3 base score of 6.5 (NVD). EchelonGraph synthesises NVD + FIRST EPSS + GHSA into a combined EG score of 7.4 (HIGH).
How do I remediate CVE-2022-31629?
A fix for CVE-2022-31629 is available: update to the fixed version the vendor names in its advisory. Fixed versions, as the CVE record's CNA (PHP Group) states them: "Upgrade to PHP 7.4.31, 8.0.24, or 8.1.11." The vendor advisories EchelonGraph has for CVE-2022-31629 are linked in the Vendor Advisories panel on this page.
